Errors and diagnostics

10.3 Data error

10.3 Data error
Data error events
FM 350-1 checks all new parameters it receives. The module reports any errors returned in
this check.
Where data errors are indicated
FC CNT_CTL1 enters the data errors and the error number in the DB of FC CNT_CTL1. You
can access this data word in the user program using the variable identifier `DA_ERR_W'.

Data error numbers and their meaning
Meaning
No error
Coding plug in wrong position or missing
The position of the coding plug does not match the programmed encoder
Invalid diagnostics value of the signal pair
Incorrect value for signal evaluation
Invalid value at the input filter for 24-V count signals
Invalid value at digital input filters
Reversal of direction not allowed
Incorrect configuration of the reaction of DO0
Incorrect configuration of the reaction of DO1
Pulse duration out of limits
Wrong operating mode selected
No gate or both gates defined
Faulty parameters of main count direction
Count high limit exceeded
A count direction other than set at the hardware interrupt parameter `Reaching the
comparison value in up or down count direction' was defined in the configuration of the
Outputs `Active on reaching the comparison value of the pulse duration for up or down
counts'. The directions set must match.
Gate control interrupts are only possible in modes with gate control.
Interrupt on reaching comparison values is not allowed when the output reaction "Active
within the range between the comparison value and overflow" or "Active within the range
between the comparison value and underflow".
Interrupt triggering at the zero transition is not allowed
Wrong coding of the "Latch Setting"
Faulty gate control parameters
