When planning an application, we recommend the following procedure:
Select the I/O modules according to your requirements. Where possible, use
PCD3 I/O modules with 16 connections; these have 16 red LEDs.
From the number of I/O modules, calculate the required number of module
holders. Check that the number of module holders is allowed:

1) Using digital I/O modules PCD3.E16x or A46x with 16 I/Os each
2) On all PCD3 units, address 255 is reserved for the watchdog. The I/Os reserved for the watchdog cannot be used,
and no analogue and H modules can be used on the sockets with base address 240
Arrange module holders in row(s) according to the mounting area avaliable
