Description of formal parameters
The table below lists all formal parameters of the M:N function.
Formal parameters of M:N function
Signal Type Type Remark
Ack I BOOL Acknowledge interrupts
OPMixedMode I BOOL Mixed operation deactivated for OP without M:N capability
ActivEnable I BOOL Function is not supported. Control panel switchover
