Address Scheme for Inputs and OutputsΒΆ
The Communication Module I/Os are addressed as follows (two-stage process):
%I(Q)B:strong:Communication ModuleNumber.ByteCommunication Module
No Communication Module numbers are assigned to I/Os that are connected to the CPU. These I/Os are configured with the PLC configuration in Automation_Builder.
I/Os connected to the basic unit are assigned to the following address areas:
| I/O Bus: | %IB0 .. | %IB999 | and %QB0 .. | %QB999 |
| COM1: | %IB1000 .. | %IB1999 | and %QB1000 .. | %QB1999 |
| COM2 : | %IB2000 .. | %IB2999 | and %QB2000 .. | %QB2999 |
| FBP slave: | %IB3000 .. | %IB3999 | and %QB3000 .. | %QB3999 |
| Onboard I/O | %IB4000 .. | %IB4095 | and %QB4000 .. | %QB4095 |
- Addressing of the digital channels is done byte-oriented.
- Motorola byteorder is used to access the inputs and outputs.
