SETI - Set Immediate Coil
The Set Immediate Coil (SETI) instruction turns ON the specified discrete output point at that point in the PLC scan instead of waiting to turn it ON as part of the normal I/O cycle at the bottom of the PLC scan. Once the discrete output point is SET ON, it will remain ON until it is turned OFF, typically via a Reset Immediate (RSTI) instruction. This instruction will only operate with the High-Speed on-board discrete outputs of the BRX 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 ON, and it is NOT necessary for the code-block containing the instruction to remain enabled for the discrete output point to remain ON.
A Set Immediate operation is typically paired with Reset Immediate operation. As such, it is advisable that you avoid referencing the same discrete output points with OUT or OUTI instructions that are referenced with SET / RST or SETI / RSTI pairs of instructions.
Parameters:
Note: Use the F9 key 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.
Element Reference specifies the discrete output point to immediately turn ON. 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.
