M238 System Functions
To obtain a diagnostic on HSC and AS-Interface Expansion modules, you can use:
HSCGetDiag (see Modicon M238 Logic Controller, High Speed
Counting, M238 HSC Library Guide) Function Block for the
TM200 HSC206D module
ASI_MasterStatusCheck (see Modicon M238 Logic Controller,
Programming Guide) for the TWDNOI10M3 module
The following example describes a method using GetRightBusStatus for I/O
expansion bus and analog modules diagnostic:
VAR
(*Modules 1 to 7 conf diag = MyRightBusStatus bits 1 to 7*)
MyRightBusStatus: WORD;
(*Modules 1 to 7 diag codes*)
ModuleError:Array [1..7] of WORD;
END_VAR
(*Conf diagnostic on expansion bus*)
MyRightBusStatus:=GetRightBusStatus
(RIGHTBUS_GET_GEN_STATUS);
IF MyRightBusStatus0 THEN
(*Conf mismatch detected => set an alarm, check bit values...*)
END_IF;
(*Get modules diagnostic; detected error if diag 0*)
(*Limit the list to analog modules configured only*)
ModuleError[1]:=GetRightBusStatus(RIGHTBUS_GET_STATUS1);
ModuleError[2]:=GetRightBusStatus(RIGHTBUS_GET_STATUS2);
ModuleError[3]:=GetRightBusStatus(RIGHTBUS_GET_STATUS3);
ModuleError[4]:=GetRightBusStatus(RIGHTBUS_GET_STATUS4);
ModuleError[5]:=GetRightBusStatus(RIGHTBUS_GET_STATUS5);
ModuleError[6]:=GetRightBusStatus(RIGHTBUS_GET_STATUS6);
ModuleError[7]:=GetRightBusStatus(RIGHTBUS_GET_STATUS7);
