RSTI - Reset Immediate Coil
The Reset Immediate Coil (RSTI) instruction turns OFF a discrete output point at that point in the PLC scan instead of waiting to turn it OFF as part of the normal I/O cycle at the bottom of the PLC scan. This instruction is normally used to turn OFF a discrete output point that has been turned ON by a SET or SETI instruction. This instruction will only operate with one of the High-Speed on-board discrete outputs of the MPUs and with the outputs on a BRX HSIO (BX-HSIO1, BX-HSIO2) module.
It is NOT necessary for the input logic to remain ON for the discrete output point to remain OFF, and it is NOT necessary for the code-block containing the instruction to remain enabled for the discrete output point to remain OFF.
A Reset Immediate operation is typically paired with Set Immediate operation. As such, it is advisable that you avoid referencing the same discrete output points with OUT or OUTI instructions that you referenced with SET / RST or SETI / RSTI pairs of instructions.
Parameters:
Note: Use the F9 key or click the 'three dot box' at the right edge of the parameter field to open the Default Element Selection Tool (the Element Picker or the Element Browser) or use the Down-Arrow key (Auto-Complete) on any parameter field to see a complete list of the memory locations that are valid for that parameter of the instruction.
Parameter specifies the discrete output point to immediately turn OFF. This can be any of the on-board discrete outputs of BRX MPUs or one of the outputs on a BRX HSIO (BX-HSIO!, BX-HSIO2) module.
