Establishing Communications

Verifying that the
MODNIM is Logged
into the PLC
SIMATIC TI505/TI500 MODNIM User Manual
After installing and configuring the MODNIM, you should verify that the
module is properly logged into the PLC I/O map.
NOTE: The PLC I/O map is the first thing to check if the PC GOOD
(PC/NIM COMM GOOD) indicator light is off.
Connect your programming device to the PLC to verify PLC-to-MODNIM
module communication by following these steps.
1. Access the Configure I/O function menu, then execute Show.
2. Execute the Read Base function.
3. Check all the I/O points on the base that the MODNIM is installed in.
Once you have entered the appropriate commands, the programming
device displays a chart listing all slots on the base and the inputs and
outputs associated with each slot. If a row on the chart is blank, then
the corresponding base slot does not contain a module. Figure 1-14
shows a sample I/O definition chart with a MODNIM installed in Slot 1
of a four-slot base. (Refer to your TISOFT manual for detailed
instructions.)
