Using module I/O in embedded RxP

11.1.1 Using module I/O in embedded RxP
When using the module digital I/O's - which is opto isolated - it is necessary to use exter-
nal supply to power the opto isolators to the pins IO- and O+ in the "I/O" connector.
Please see chapter 2 External signals available at the MAC00-Ex4 and Ex41., page 17 for
further details.
A possible exception to this is when using MAC00-Ex41 containing extended I/O's.
If using this module it is possible to activate the two dip switches inside the module. Then
the internal power is also supplied to the opto isolators thereby eliminating the need for
external supply.
The module I/O's (2 outputs and 4 inputs in MAC00-Ex41, 1 output and 1 input in
MAC00-Ex4) are as default accessible from the PLC by writing and reading to/from the
module registers 7 and 47. Please refer to chapter 8 for further details.
If it is required to use the digital module I/O's in embedded RxP (eRxP - integrated se-
quential PLC), then this functionality has to be enabled first.
This is either done by manually manipulating the bits 7-9 in the module setup bits register
(module reg. 6), from the PLC. Please see chapter 8 for further details about the module
registers.
Or it can be done in MacTalk in the Ethernet tab by checking the "Use I/O in eRxP" as
shown below, and then pressing the "Apply and save button"

program
Then the module I/O's are visible from the eRxP in the motor. The module outputs O1,
O2 can be activated by the bits 30 and 31 in the motor error/status register (motor reg.
35). The module inputs IN1-IN4 are read in motor register 210 in the bits 2-5.
