Public variables
The following table describes the public variables:
Parameter
Data type
Meaning
AREA_NR
WORD
Automation area to be monitored.
This WORD specifies which area will be monitored by the diagnostics EFB.
It is advisable to assign the numbers according to the functional module.
AREA_NR can be a value from 0 to 15.
The standard value is 0.
Example:
Cutting: No.1
Milling: No. 2
Thread cutting: No. 3
In the example, AREA_NR must have the value 1, 2 ou 3, so that they can recognize the error affected area.
OPT_CTRL
BOOL
This bit specifies whether a diagnostic will request a user acknowledgement.
0: no user acknowledgement required
1: user acknowledgement required
The standard value is 0.
Description of T_COM_ASI_DIAG IODDT
All the information in the DFB results from the exploitation from T_COM_ASI_DIAG IODDT. T_COM_ASI_DIAG supports READ_STS, READ_TOPO_ADDR and is usable by DFB.

NOTE: Please note that, depending on your hardware platform, using ASI_DIA DFB does not give the same diagnosis:
  • Premium/ Atrium platform: ASI_DIA operates in the same way as in PL7: no indication about error slave number in case of Peripheral errors on one slave.
  • Modicon M340 platform: indication of error slave number in case of Peripheral errors on one slave.
