CS31_DIAG_EXT¶

Function Block CS31_DIAG provides the diagnosis data of the CS31 Bus to the user.

The read values are written into internal structures of the instance.

Structure

TYPE

Assignment

strVisuData1

strCS31_DiagBus

Diagnosis data of the CS31 master

strVisuData

strCS31_DiagModule

Diagnosis data of all 31 CS31 software modules

ARRAY[0..31] OF strCS31_DiagOneModule

CS31Mod

strCS31_DiagOneModule

Diagnosis data of one CS31 software module

The structure strCS31_DiagBus is composed as follows:

TYPE strCS31_DiagBus : (* STRUCT info about CS31 bus *) STRUCT
	iCS31BusState :	DINT;	(* Bit 0=1 waiting for slave Bit 1=1 initialization Bit 4=1 I/O data exchange := 19 all modules at bus *)
	iNumberModule :	DINT;	(* current no. of CS31 software modules on the CS31 bus *)
	iMaxNumberModule :	DINT;	(* max. number of modules at CS31 bus since power ON *)
	iErrorSum :	DINT;	(* sum error counter *)
	ulCycleCount :	DWORD;	(* counter of CS31 bus cycles *)
	byStateDiag :	BYTE;	(* general bus diagnosis: 0=ok, 1=no module on the bus *)
END_STRUCT END_TYPE

The structure strCS31_DiagOneModule is composed as follows:

TYPE strCS31_DiagOneModule : STRUCT
	dwScheduleCycle :	DWORD;	(* internal time *)
	byPhysicalAdress :	BYTE;	(* module address x 2 *)
	byStateDiag :	BYTE;	(* communication status:
				00 = OK Bit 0=1 (1) module disconnected again Bit 1=1 (2) module not available on bus Bit 2=1 (4) unconfigured module on bus Bit 3=1 (8) difference in I/O range Bit 4=1 (16) E4 – error message Bit 5=1 (32) Bit 6=1 (64) *)
	bySlaveType :	BYTE;	(* Slave type:
				00 = digital input 01 = analog input 02 = digital output 03 = analog output 04 = digital input/output 05 = analog input/output 06 = special module
	byInputBytes :	BYTE;	(* number of reported input bytes *)
	byOutputBytes :	BYTE;	(* number of reported output bytes *)
	byInputBytesConf :	BYTE;	(* number of input bytes in configuration *)
	byOutputBytesConf :	BYTE;	(* number of output bytes in configuration *)
	byModuleConf :	BYTE;	(* 1-PLC config, 3- ignore module *)
	byStateDiag :	BYTE;	(* internal flag *)
	byd1 :	BYTE;	(* internal flag *)
	usErrorCounter :	WORD;	(* single-error counter *)
	byDiagErr :	BYTE;	(* internal error number *)
	byDiagChannnel :	BYTE;	(* internal error channel *)
	byd2 :	BYTE;	(* internal flag *)
	byd3 :	BYTE;	(* internal flag *)
	pConfig :	DWORD;	(* internal flag *)
	END_STRUCT END_TYPE

The structure strCS31_DiagModule contains an ARRAY[0..31], i.e. with 32 entries of the structure strCS31_DiagOneModule.

This way, the structures strVisuData1 and strVisuData provide access to all diagnosis data of the CS31 bus.

If the user program should have access to these values, this is done as follows:

diagCS31ext.strVisuData1.Variable.

In the following example, the current number of CS31 modules is read and assigned to the variable byActNumCS31Module:

The most important data are available in the visualization Visu_CS31_Diag_EXT of the Function Block Visualizations.
