The 2IN-2OUT-SIG-CO Controller has a limitation of a maximum of 4 errors in the list. If the device
registers more errors, the list will be truncated, and the oldest entries will be lost.
The error codes stored in the list are 32-bit unsigned numbers, consisting of two 16-bit fields. The
lower 16-bit field is the EMCY error code, and the higher 16-bit field is a manufacturer-specific
code. The manufacturer-specific code is divided into two 8-bit fields, with the higher byte indicating
the error description, and the lower byte indicating the channel on which the error occurred.

EMCY Error Code
If node-guarding is used (not recommended per the latest standard) and a lifeguard event occurs,
the manufacturer-specific field will be set to 0x1000. On the other hand, if a heartbeat consumer
fails to be received within the expected timeframe, the Error Description will be set to 0x80 and the
Channel-ID (nn) will reflect the Node-ID of the consumer channel that was not producing. In this
case, the manufacturer-specific field will therefore be 0x80nn. In both cases, the corresponding
EMCY Error Code will be the Guard Error 0x8130.
If
an RPDO is not received within the expected “Event Timer” period, an RPDO timeout will be
flagged. Table 36 outlines the resulting Error Field Codes and their meanings.
