Transistor Remote I/O Terminals with 3-tier I/O Terminal Blocks Section 4-4
Setting Pins 3 and 4 The functions of pins 3 and 4 differ for inputs and outputs, as shown in the fol-
lowing diagram.
Pin 3: Reserved (Always OFF)
Pin 4: As follows:
Inputs: No function (Always OFF)
Outputs: Hold/Clear outputs for communications error
OFF (Clear): All output data from the Master will be cleared to 0 when a
communications error occurs.
ON (Hold): All output data from the Master will be retained when a
communications error occurs.
Pins 3 and 4 are factory-set to OFF.
