| **** SPRB Error Tolerance| Contains the absolute value of the maximum allowable discrepancy between the current setpoint readback value and the setpoint value written by SMOC at the previous execution before SMOC flag a readback error. The control mode becomes Standby and Message 152 is generated. In order to return to Control mode after the error is reset, turn on Desired Status from Standby and Control again.

| Essential for Control| TRUE- is selected when MV is essential for control. FALSE -(Default) is selected when MV is not essential for control. Selection of ¨TRUE〃 provides following effect.
