MPINO STUDIO 2 Phase 4-8 · Logic Control Box Functions
These commands change the ladder execution position or control an execution zone.
This ladder screen contains a JMP path and an MCS zone.
1. JMP and JMPN
JMP
Jump
When the left condition is ON, moves to a later label in the same ladder and skips the ladder rows between. Skipped outputs and calculation targets retain their previous values.
Syntax: JMP L1
Arguments
- 1st = label: label name to jump to (any alphanumeric, must match a label entered in a cell)
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition ON | Outputs and calculation targets before L1 | JMP L1 | Rungs up to L1 are skipped; their values are held |
JMPN
Jump if Not
When the left condition is OFF, moves to a later label in the same ladder. Its other behavior and limits are the same as JMP.
Syntax: JMPN L1
Arguments
- 1st = label: label name to jump to (any alphanumeric, must match a label entered in a cell)
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition OFF | Outputs and calculation targets before L1 | JMPN L1 | Rungs up to L1 are skipped; their values are held |
2. MCS and MCSCLR
MCS
Master Control Set
Starts a master control zone at a level from 0 to 15. When the left condition is OFF, coils in the zone up to the matching MCSCLR are processed as OFF.
Syntax: MCS 0
Arguments
- 1st = level: 0 to 15; use lower numbers for outer zones
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| Left condition OFF | MCS 0 zone | MCS 0 | Zone coils are OFF; calculation and transfer targets hold |
MCSCLR
Master Control Clear
Ends the master control zone at the specified level and any inner zones.
Syntax: MCSCLR 0
Arguments
- 1st = level: the same number from 0 to 15 as the MCS to end
| Run condition | Before | Command entered | Expected result |
|---|---|---|---|
| After MCS 0 | Level 0 zone is active | MCSCLR 0 | Ends level 0 and its inner master-control zones |
3. Troubleshooting
| Symptom | What to check |
|---|---|
| The jump label cannot be found. | Check for a label with exactly the same spelling in the same ladder. |
| Outputs outside the MCS zone turn OFF. | Check the MCS and MCSCLR level numbers and nesting order. |
