The structure of status data

 

TOP

Status register, Fault register, and Fault Unmask Register

Bits “1” and “0” of the status register and the status enable register represent “set” and “reset,” respectively. The fault register is read and reset using FAU?.

 

Bit Bit Name Description
7 OPP (Over power protection) Indicates that the overpower protection (OPP) has tripped.
6 PL (Power limit) Indicates that the PWR is operating under power limitation (PL).
5 OUT Indicates that outputs are ON.
4 OCP (Over current protection) Indicates that the overcurrent protection function of the connected power-supply unit is activated.
3 OHP (Over heat protection) Indicates that the overheat protection function of the connected power-supply unit is activated.
2 OVP (Over voltage protection) Indicates that the overvoltage protection function of the connected power-supply unit is acctivated.
1 C.C (Constant current) Indicates that the connected power-supply unit is operating at a constant current.
0 C.V (Constant voltage) Indicates that the connected power-supply unit is operating at a constant voltage.

Status byte register and Service request enable register

Bits “1” and “0” of the status byte register and the service request enable register represent “set” and “reset,” respectively.

 

Bit Bit Name Description
7 PON (Power ON) Indicates that power has been supplied to the PIA4800 series (except for the PIA4850). Use the DIP switch on the rear panel to specify whether to use this register.
6 RQS (Request) Indicates that a service request has been issued. Reset when read using a serial poll.
5 NOT USED Not used in the controller.
4 Reserve Used by the accompanying software utility.
3 ERR (Error) Indicates the occurrence of an error.
2 SHUT DOWN Indicates that the SHUT DOWN signal has been applied .
1 NOT USED Not used in the controller.
0 FAU (Fault) Indicates that a bit of the fault register on a channel has been set.

7 NOT USED Not used in the controller.
6 NOT USED Not used in the controller.
5 NOT USED Not used in the controller.
4 COMM (Communication) Represents a communication error.
3 CONN (Connection) Indicates that an unrecognized device has been accessed.
2 VAL (Value) Represents an error exceeding a value range.
