Cause E󹪜ect Remedy
5 Internal error, system error The "PNFault" LED is activated.
The outputs are switched o󹪜.
1)
The value 0x80 is stored in status byte 1.
The 󹪝rmware has detected a system error,
this status can only be exited by means of
a switch-on / switch-o󹪜.
6 Range exceeded at the inputs Check input circuit and adjust, if required.
7 Range exceeded at the out‐
puts
Correct the values in the user program.
1)
The analog outputs retain their last speci󹪝ed value.
Diagnostics via status bytes 0/1
In status byte 0, the set operating modes are re󹪞ected e.g. "0x55" if control byte 0 = 0x55 has
been speci󹪝ed (voltage on all channels).
In the event of an error, the error bit is set in status byte 1 (bit 7). In the event of an error in one
channel, all channels are deactivated.
