ENDMCR
Use the End Master Control Relay (ENDMCR) function to resume normal program execution after
an MCR function. When the MCR associated with the ENDMCR is active, the ENDMCR causes
program execution to resume with normal power flow. When the MCR associated with the
ENDMCR is not active, the ENDMCR has no effect.
Logicmaster 90-30/20/Micro software supports two forms of the ENDMCR function, a non-nested
and a nested form. The non-nested form, ENDMCR, must be used with the non-nested MCR
function, MCR. The nested form, ENDMCRN, must be used with the nested MCR function,
MCRN.
The ENDMCR function has a negated boolean input EN. The instruction enable must be provided
by the power rail; execution cannot be conditional. The ENDMCR function also has a name, which
identifies the ENDMCR and associates it with the corresponding MCR(s). The ENDMCR function
has no outputs; there can be nothing before or after an ENDMCR instruction in a rung.
