140CPU43412A Firmware Part I

Click now to view our blog on the 140CPU43412A Configuration and Setup. 

140CPU43412A Firmware

The q5rv144e.bin file supports both Concept (IEC & 984) and ProWORX PLCs.

In order to restore a 140CPU43412U (Unity) to a 140CPU43412A (Concept), three main phases are required.

Phase 1 – Restore the PLC to Concept with an intermediate OS. 

Phase 2 – Power OFF then ON the PLC. 

Phase 3 – Restore the Operating System with the appropriate file.

These phases are mandatory and cannot be by-passed.

Phase 1: 

Launching the OS Loader

The OS loader (provided with Unity) allows the user to download the Operating System to the PLC. To open it click on Start/Program/SchneiderElectric/Unity-PRO/OS loader.

Select the Communication Protocol

From the main screen of the OS loader, click on the “Next” button. To download the Operating System into the PLC, select the right communication protocol (in accordance with established physical link) and click on the “Next” button.

Select the Target Device

On the Device Type field, select Processor and the other needed parameters (Modbus address….). Then connect to the selected PLC (Node).

Select the Download Function 

From the screen described above press the “Next” button. A new screen is proposed: select “Download OS to device”.

Select the File to be Downloaded

Click on the “Browse…” button in order to select the file to download into the PLC. In this example we will restore the OS from 140CPU43412U to 140CPU43412A firmware. For that select the following folders: Quantum\Processor_modules\Unity_to_Concept. To restore the OS from Unity to Concept, two binary files can be selected:  Unity_to_Concept_43412A.bin (allows to “format” the processor to Concept)  q5rv135E.bin is the OS that will finally be downloaded in the processor. In our example we have to “format” the processor (remember, we still are in the Phase 1) then select and Validate “Unity_to_Concept_43412A.bin”. Once done click on the “Next” button.

Download the Intermediate OS

Once the previous screen is validated a warning is displayed: Click the “Okay” button. Two screens that give information regarding the file, the processor and the download are now displayed. Note: If the system detects a discrepancy on the hardware or on the OS version, the download will not be possible. This is indicated by a red cross and the “Next” button becomes unavailable. Solve this issue and continue. When the hardware – OS are compatible, click on the “Download” button to launch the download of the intermediate OS file.

140ARI03010 Configuration and Setup

You can check out our previous blog post on the 140ARI03010 here for more information.

140ARI03010 Terminal Strip Keying

Field wiring terminal strips and module housings in the 140ARI03010 configuration are slotted on the left and right sides of the PCB card slot to accept keying pins (see I/O Module figure). The purpose of keying is to prevent plugging the terminal strip into the wrong module, once wiring connections have been made. Keying is implemented at the discretion of the user.

Primary keying is provided on the right side of the 140ARI03010 configuration, marked A through F (top and bottom positions are coded the same). Primary keying provides module class coding. Primary codes have been pre-defined (see the following chart). Secondary keying is provided on the left side of the module, marked 1 through 6. Secondary keying codes are user-definable and may be used to identify module personality within module classes, or other unique site requirements. To support keying, all 140ARI03010 modules accepting terminal strips come with 12 customer- installable primary keys (six yellow keys each for the module and terminal strip) and six secondary keys (three white keys each for the module and terminal strip).
To implement the user-optional secondary keying code (designed to prevent the mismatching of terminal strips to I/O modules of identical type), 17 slot positions have been provided in modules and terminal strips to support a variety of coding schemes.
In addition (by using the secondary keying code), the user may key the field wiring terminal to the position where the module is installed in a backplane, using the white keys for each code.
140ARI03010 Map Status
The Quantum I/O map menu entry allows you to assign the 3x register that defines the start of a table in which I/O-mapped module status is available. You may either enter the 3x value, or the value 0 (indicating no choice). The value entered is displayed in the summary information on the top of the Quantum I/O Map. Modules in a backplane report status (and fault) information in an 8-bit byte—therefore, one word of the table conveys the status information for two modules

6SN1145-1BA01-0BA1 Configuration and Setup

You can view our previous blog post on the Siemens 6SN1145-1BA01-0BA1 manual here for more information.

Drive Line-Up
The Siemens 1P 6SN1145-1BA01-0BA1 configuration is modular, comprising line filter, commutating reactor, line supply infeed module, drive modules as well as, when required: monitoring, pulsed resistor and capacitor module(s). Satisfactory operation is ensured only in conjunction with the components that are described in the Configuration Manual or published in the Catalog NC60 (Internet Mall) and with adherence to the required boundary/application conditions. In order to avoid contamination, the modules should be installed in a control cabinet with degree of protection IP 54. Modules can also be arranged in several tiers one above the other or next to one another.

Due to the limited conductivity of the DC link busbars of the modules with module width 150 mm, the DC link power PZK of the Siemens 6SN1145-1BA01-0BA1 configuration must not exceed 55 kW. Larger DC link busbars must be used if this restriction cannot be complied with. The DC link power PZK of the subsequent modules is calculated according to the engineering rule specified in Chapter 1.3 of the manual. The larger DC link busbars can be ordered as a set with Order No. [MLFB] 1P 6SN1161–1AA02–6AA0. The set includes reinforced DC link busbars for module widths 50 mm, 100 mm and 150 mm. The standard DC link brackets between the modules may not be changed, even when strengthened DC link busbars are used.

140ACI04000 Configuration and Setup

You can check out our previous blog post on the 140ACI04000 manual here for more information.

140ACI04000 Wiring Configuration Overview
The Modicon 140ACI04000 module option processor provides Quantum Series controllers with the high availability and security critical process applications demand. Central to the system is the standby controller with current system status for automatic switchover in the event of a primary controller failure. This means critical processes are unaffected by control system hardware failures. The result – productivity goes up while downtime is minimized.
At the beginning of every primary controller scan, the current register and I/O state table is transferred to the Hot Standby across a high-speed, secure fiber optic communication link. In the event of a primary controller failure, the standby option processor takes control of the system with up-to-date I/O and register status information for a bumpless, controlled transfer with minimal process impact. Critical processes which cannot tolerate any disruption of control are assured a fast, smooth switchover, allowing the 140ACI04000 resolution.
Features / Benefits
  • A single-board Modicon Hot Standby option processor in each controller system improves reliability by eliminating the intermediate supervisor controller.
  • System control transfers occur in either direction increasing system uptime by eliminating the master-slave relationship.
  • Integrity of the user programs are verified and compared in both controllers to ensure high security.
  • High-speed fiber optic communication link between processors minimizes scan impact and improves productivity.
  • Primary I/O state table transfers to the standby controller every scan or in multiple scans providing up-to-date system status and higher system integrity.
  • Software control of Modbus and Modbus Plus ports allows host computer communications to either controller with no custom communication drivers.
  • New configuration extension mode provides greater flexibility in state RAM transfer.
  • An optional ladder logic function block delivers an easy migration path for 984/800 Series hot standby users.
  • The Hot Standby system is compatible with all Modicon TSX Quantum controllers and S908 remote I/O systems for cost-effective system design

140CPU43412A Configuration and Setup

You can check out our previous blog post on the 140CPU43412A manual and configuration here for additional setup info.

Front Panel Topology
There are two switches (a three-position slide switch and a three-position key switch) located on the front of the 140CPU43412A configuration. The module has a single slide switch that is used to select the comm parameter settings for the Modbus (RS-232) ports.
Rear Panel Topology

The address switch, which is comprised of two rotary switches, is located on the rear panel of the Quantum CPUs. The address switch is used for setting Modbus Plus node and Modbus port addresses. SW1 (the top switch) sets the upper digit (tens) of the address, SW2 (the bottom switch) sets the lower digit (ones) of the address. The illustration below shows the correct setting for an example address of 11.

Option Module Interface Support

The 140CPU43412A firmware supports up to six network modules (i.e., Modbus Plus, Ethernet, and Multi-Axis Motion option modules) using the option module interface technique. However, only two Modbus Plus modules can have full functionality, including Quantum DIO support.
