PLC MONITOR P3/4
PLC 107-100
PLC 107-100 (MP-121) displays the status of PLC bits 107-100. A “1” in any bit indicates that the output is “active”.
The digital outputs are active low (current sinking). Page one of the “Help” screen displays the bit map for PLC 107-
100. Also refer to Appendices: Appendic C.
PLC 115-108
PLC 115-108 (MP-122) displays the status of the internal PLC control bits 115-108. A “1” in any bit indicates that the bit
is “active”. These internal bits (control relays) can be used as global “control relays”. For example, they can be used
to create one-shots or latches. They can also be used to simplify programming. Page one of the “Help” screen displays
the bit map for PLC 115-108. Also refer to Appendices: Appendic C.
PLC 123-116
PLC 123-116 (MP-123) displays the status of the internal PLC control bits 123-116. A “1” in any bit indicates that the
bit is “active”. Page one of the “Help” screen displays the bit map for PLC 123-116. Also refer to Appendices:
Appendic C.
PLC 131-124
PLC 131-124 (MP-124) displays the status of the internal PLC control bits 131-124. A “1” in any bit indicates that the
bit is “active”. Page one of the “Help” screen displays the bit map for PLC 131-124. Also refer to Appendices:
Appendic C.
PLC 139-132
PLC 139-132 (MP-125) displays the status of the internal PLC control bits 139-132. A “1” in any bit indicates that the
bit is “active”. Page one of the “Help” screen displays the bit map for PLC 139-132. Also refer to Appendices:
Appendic C.
PLC 147-140
PLC 147-140 (MP-126) displays the status of the internal PLC control bits 147-140. A “1” in any bit indicates that the
bit is “active”. Blk Sel A, B, C select the block that is active, if Blk Sel Source (CP-478) has been set to “1” (DgIn). Page
one of the “Help” screen displays the bit map for PLC 147-140. Also refer to Appendices: Appendic C.
PLC 155-148
PLC 155-148 (MP-127) displays the status of the internal PLC control bits 155-148. A “1” in any bit indicates that the
bit is “active”. Page one of the “Help” screen displays the bit map for PLC 155-148. Also refer to Appendices:
Appendic C.
PLC 163-156
PLC 163-156 (MP-128) displays the status of the internal PLC control bits 163-156. A “1” in any bit indicates that the
bit is “active”. Page one of the “Help” screen displays the bit map for PLC 163-156. Also refer to Appendices:
Appendic C.
PLC 171-164
PLC 171-164 (MP-129) displays the status of the internal PLC control bits 171-164. A “1” in any bit indicates that the
bit is “active”. Page one of the “Help” screen displays the bit map for PLC 171-164. Also refer to Appendices:
Appendic C.
PLC 179-172
PLC 179-172 (MP-130) displays the status of the internal PLC status bits 179-172. None of these bits are presently
active. They are reserved for future use. Page one of the “Help” screen displays the bit map for PLC 179-172. Also
refer to Appendices: Appendic C.
