PROSOFT MVI56-MCM Communication module

Wiring Connections and Cabling The IMASI13 module has three card edge connectors to supply power (P1), connect I/O expander bus communication (P2), and provide analog inputs (P3). Wiring Install the analog input module in the module mounting unit to connect the module to the +5 VDC voltages needed to power the circuits. The module mounting unit also connects P2 to the I/O expander bus for communication with the controller. P1 and P2 connection require no additional wiring or cabling. NOTE: A dipshunt on the backplane of the module mounting unit connects the I/O expander bus between the ASI module and the controller. Locate the module so the bus can connect to them or they will not communicate.

Cable Connections 

The IMASI13 module uses one NTAI06 termination unit for termination. The NTAI06 requires an NKAS01 or NKAS11 cable to connect to the IMASI13 module. The cables have a Y configuration with two connectors on one end. Note the labeling of J2 and J3 to insure proper connection of the input signals. Figure 3-5 shows cable connections to the NTAI06 termination unit.

Configuration and Calibration Section

 This section explains the configuration and optional field calibration for the field inputs of the IMASI13 module (ASI). Function codes in the controller configure the IMASI13 module and identify the active analog inputs. These function codes specify the I/O expander bus address of the ASI module and the number of active channels on the input module. Module calibration is performed during module assembly at the factory. Circuitry and software in the module make automatic adjustments to compensate for application variations, component drift, and cold junction errors. The ASI module does provide for field calibration although it should not be required.
