Code Description
5206
BAD MESSAGES
This diagnostics counter increases by one every time the ACS 160 finds
any kind of communication error. During normal operation, this counter
hardly ever increases.
5207
GOOD MESSAGES
This diagnostics counter increases by one every time a valid Modbus
message has been received by the ACS 160. During normal operation, this
counter increases constantly.
5208
BUFFER OVERRUNS
The longest possible message length for the ACS 160 is 32 bytes. If a
message exceeding 32 bytes is received, this diagnostic counter increases
by one every time a character is received and cannot be placed in the
buffer.
5209
FRAME ERRORS
This diagnostic counter increases by one every time when a character with
a framing error is received from the bus.
• Communication speed settings of the devices connected to the bus
differ.
• Ambient noise levels may be too high.
5210
PARITY ERRORS
This diagnostic counter increases by one every time when a character with
a parity error is received from the bus.
• Parity settings of the devices connected in the bus differ.
• Ambient noise levels may be too high.
5211
CRC ERRORS
This diagnostic counter increases by one every time when a message with
a CRC error is received.
• Ambient noise levels may be too high.
• CRC calculation is not performed correctly.
