Planning an application
Guidance

- If an application is mounted in a single row (max. 15 module holders), then
after five PCD3.C100 a PCD3.C200 must be used to amplify the bus signal
(unless the configuration ends with the fifth PCD3.C100 or PCD3.C110).
- If the application is mounted in multiple rows, the restricted length of cable
means that only three module holders (1× PCD3.C200 and 2× PCD3.C100)
may be mounted in one row.
The following procedure is recommended to plan an application:
Select the I/O modules according to the requirements.
For digital PCD3 I/O modules, if possible use those with 16 connections,
these have one LED per digital I/O.
Calculate the required number of module carriers according to the number
of I/O modules. Check if the number of module carriers is permitted:

2) The address 255 is reserved for the watchdog on all PCD3. The I/O reserved for the watchdog can not be used by
the user, and analog and H modules must not be deployed with the slots with base address 240
Arranging the module carrier in series according to the available mounting
surface and thereby determining the connection material:
