2-16 Module Operation

Output Start Up and Enabling

When the SLC processor is not in run mode, the module outputs are
disabled. After the SLC processor enters run mode, the module
examines the Direct Output fields (O:e.0/0-7).

All outputs under module control are disabled until after the module
configuration has been completed and the Function Control bit has
been set to 1. If the Function Control bit is returned to 0 the module
controlled outputs will again be disabled. The user program
controlled outputs are not affected by the Function Control bit.

When reset to 0, the Enable Outputs bit (M0:e.1/1) disables module
and user program controlled outputs.

Operating Mode

The Operating Mode field (M0:e.1/14-15) is used to select the
module’s mode of operation. The field is specified as follows:
