S:26User control bits
S:26/00 Restart/continuous SFC: when reset, controller restarts at first step in SFC.
When set, controller continues with active step after power loss or change to
RUN
S:26/01 Start-up protection after power loss: when reset, no protection. When set,
controller sets major fault bit S:11/5 when powering up in run mode.
S:26/02 Define the address of the local rack: when reset, local rack address is 0. When
set, local rack address is 1.
S:26/03 Set complementary I/O (series A only): when reset, complementary I/O is not
enabled. When set, complementary I/O is enabled.
S:26/04 Local block-transfer compatibility bit: when reset, normal operation. When set,
eliminates frequent checksum errors to certain BT modules.
S:26/05 PLC-3 scanner compatibility bit: when set (1), adapter channel response
delayed by 1 ms; when reset (0) operate in normal response time.
S:26/06 Data table-modification inhibit bit. When set (1), user cannot edit the data
table or modify forces while the controller keyswitch is in the RUN position.
