3.6 Module Login Verification
After the NIM has been installed and configured, you should verify that the
NIM is logged into the controller I/O map. This is the first thing you should
do if the PC/NIM Comm Good LED is not on.
Connect a programming device to the controller to verify controller-module
communication.
To do this in a 520/530 P/C system with a VPU200–3102, enter AUX 43,
which checks all I/O points on a particular base. If you have a 520/530
system with a VPU200–3104, press F3 and use the CONFIO function.
If you have a 520/530C or 560/65 controller system with a VPU200–3104,
press F3 for the CONFIO function, then F2 for SHOW, and then F5 for
READ BASE. This sequence allows you to check all I/O points on the base
that the NIM is installed in.
Once you have entered the appropriate command, the controller will
respond with a chart listing all slots on the base and the inputs or outputs
associated with each slot. If a row on the chart is blank, then the
corresponding base slot does not contain a module.
To verify the installation, look in the chart for the slot number
corresponding to the right-most slot of the two slots occupied by the module.
If an “S” or “SF” (special function) and word memory locations appear on
this line, the module is registered in the controller memory and you can
proceed with the usual operations. If the line is blank or erroneous, you
should check the NIM to be sure it is firmly seated in the slots and enter the
appropriate command again. If you still cannot verify the installation, you
should contact your local distributor or the Siemens Technical Services
Group at 423–461–2501 for further assistance.
