SIMATIC TIWAY I Series 500 NIM User Manual
3.2 Installing the NIM
This section describes how to mount the NIM in the Series 500 I/O base,
connect the communication cables to the NIM, and initialize the system for
operation. The programmable controller (P/C) and the programming device
should be in place before you install a NIM.
Before inserting the NIM into the I/O base, first determine which two
adjacent slots that the NIM will occupy. If necessary, it is possible to place
the NIM in the left end slot, although it will extend beyond the edge of the
I/O base.
!WARNING
Do not insert or remove the NIM while power is applied to the base, since doing
this may cause personal injury, alter controller memory, cause a controller fatal
error, or damage the module.
Until you disconnect power to the I/O base, hazardous voltages are present.
Inserting or removing the NIM before disconnecting power to the base could
cause death or serious injury to personnel, and/or damage to equipment; it
could also alter CPU memory, cause a CPU fatal error, or damage the NIM.
Do not insert or remove the NIM while power is applied to the base.
Complete the following steps to install the NIM.
1. Disconnect power to the I/O base.
2. Insert the module into the two adjacent I/O base slots you have chosen.
3. Set the configuration dipswitches.
4. Power up the I/O base.
5. Check the NIM indicator lights to be sure the module is operating
correctly.
6. Use a programming device to verify that the NIM is logged into the
controller.
7. Connect the network cables to the NIM.
The following paragraphs provide detailed information for each step.
