The 140CRA31200 is a Ethernet RIO drop adapter in the Modicon Quantum series. It has 3 ports and uses the Ethernet IP/Modbus TCP communication port protocol. It can handle two integrated connection types: the Ethernet IP/Modbus TCP through the service port or through the device network. It is compatible with the 140CRP31200.
The 140CRA31200 has a number of local signalling channels. 1 green LED for RUN, 1 green/red LED for module status, 1 green/red LED for network communication status, and 1 red LED for I/O. This adapter module consumes one slot in the main (first) rack of the in Quantum remote drops. The extended (second) rack in a Quantum remote I/O drop does not require an adapter.
To set the location of the Ethernet remote I/O drop on the network, use the rotary switches on the front of the 140CRA31200 before you apply power to the module and before you download the application. The values that are set are applied during a power cycle. If the switch settings are change after the module has powered up, the Mod Status LED is activated and a mismatch message is logged in the module’s diagnostic system.
Because new values on the rotary switches are implemented on at the next power cycle, it is recommended that you set the values before starting the module. Valid values are from 00 to 159. These rotary switches can be manipulated on the 140CRA31200 with a small flat tipped screwdriver, and no software is required to configure or enable the rotary switches. Do not use the Stored and Clear IP settings on the Ones rotary switch, and keep in mind that the functionality of these settings do not apply to remote I/O installations.
