EWA 4NEB 811 6149-02
= Error group ( 5.5.2 of the Manual)
(Progr. No.; Consec. No. 5.4.1)
The following assignments apply in the case of
error messages with "I/O identifier" in byte 3:
I/O identifier:
Word No. (0 to 63) of DI module,
Word No. (0 to 63) of CH DQ,
but not the CH relay DQ module for connecting sensors or the CH
AQ module in the case of AI modules;
Bit No.;
Word No. (0 to 62) of the CH relay DQ in AIs
I/O Identifier in DI Error Messages:
Bit 3 to 0 = 0001
Bit 4 = 0 DI without
= 1 DI with CH DQ
Bit 5 = 0 not used
Bit 6 = 0 CH DQ
= 1 CH DQ
Bit 7 = 0 H DQ
= 1 CH DQ
I/O Identifier in DI Error Messages:
Bit 3 to 0 = 0010
Bit 4 = 0 DQ without R DI
= 1 DA with
Bit 5 = 0 not used
Bit 6 = 0 R DI
= 1 R DI
Bit 7 = 0 R DI
= 1 R DI
I/O Identifier in DI Error Messages:
Bit 3 to 0 = 0100
Bit 4 = 0 AI without
= 1 AI with
Bit 5 = 0 AI with 1 sensor,
CH Rel DQ in the same subunit as CH AQ
1 AI with 2 sensors
CH Rel DQs in both subunits
Bit 6 = 0 CH AQ
= 1 CH AQ
Bit 7 = 0 CH AQ
= 1 CH AQ
