• Msg Recv, counts packets successfully received by the module
• Recv Timeouts, applies only when the module is the DCS master.
They occur when a reply packet isn’t received within the timeout
period.
• CRC Errors, counts packets received with CRC errors
• OverRun Errors, counts packets received that are longer than 272
bytes
• Abort Errors, increments when the module starts to receive a packet
but the packet is never completed, for whatever reason
AutoMax Diagnostic counters apply to both DCS and Remote I/O
operation.

last power on or reset
Rx Rx Bus
Timeout the number of receiver bus timeouts since the last
power on or reset
Tx Bad CRC the number of transmitter bus timeouts since the last
power on or reset
Tx Bus Timeout the number of transmit bus timeouts since the last
