ERROR 0
A general error has occurred. This bit is set if a FRAME or SSI IN error has
occurred.
An incorrect data frame exists, i.e. the data frame is not terminated with zero
(possible wire break of clock lines).
The SSI input of the I/O module is at low level if there is no data transmission.
Possible causes are:
• SSI has no power supply
• Wire break on SSI data inputs +D or -D
• Data lines switched
