x =
x = Data block number (DB)
: KS = P Normal 1/0 area
P/Q
Extended 1/0 area
KS = Q
PAFE : In case of illegal parameterization the signal status is"1". The recognized error is
then shown by the assignment of the flag byte FY 255:
F 255.0 The module address is outside of the specified area or not within the
8–bit grid pattern (first part of parameter BGDB).
The parameter P/Q is not set with 'P-' or
F 255.1
(not for programmable controller S5-115U)
The specified user data block number is zero or one.
F 255.2
(one only for S5-155U andS5-115U)
(second part of parameter BGDB)
F 255.3 The specified user data block does not exist or is too short.
(second part of parameter BGDB)
F 255.4
QVZ, no module found under this address.
(first part of parameter BGDB)
(only for S5-155U and S5-135U)
F 255.5 When the "verify–read (PR)" or "calculate average value (MB)"
special function is enabled, the "number" parameter is located
(outside the permissible area from O to 15) in data word DR 182 or DR
184 of the user data block.
