Consume Status Variables for Bindings
To test values for the binding status, create these defined words in the dictionary for a project:
Status Message | Value | Description |
|---|---|---|
SNCP_KVB_ERR_BINDING_READY | 0 | Normal steady state data exchange. The binding link is healthy. |
SNCP_KVB_ERR_BINDING_IN_PROCESS | 1 | Producer and consumer are in the process of connecting |
SNCP_KVB_ERR_UPD_IN_PROCESS | 2 | Producer and consumer are in the process of reconnecting following an online update |
SNCP_KVB_ERR_UPD_TIMEOUT | 3 | Producer and consumer did not reconnect within Update Timeout milliseconds following an online update |
SNCP_KVB_ERR_NO_PRODUCER | 4 | At the beginning of a connection or following Bind Response Timeout milliseconds during data exchange |
SNCP_KVB_ERR_BAD_CRC | 5 | Producer and consumer binding table CRC mismatch during connection |
SNCP_KVB_ERR_IMPOSSIBLE_TO_BIND | 6 | Conversion of structures not supported on heterogeneous binding link |
SNCP_KVB_ERR_IP_DENIED | 7 | Producer only error, indicating a consumer with an unknown or unexpected IP address is requesting binding links. The link is denied. |
SNCP_KVB_ERR_BAD_PRODUCER_ID | 8 | Producer only error, indicating the producer has received a binding link request from a consumer containing an unexpected producer identity. The link is denied. |
SNCP_KVB_ERR_BAD_GROUP_ID | 9 | Producer only error, indicating the producer has received a binding link request from a consumer but the request does not contain a known bound variable group identity. The link is denied. |
SNCP_KVB_ERR_BAD_BUFF_SIZE | 10 | Producer only error, indicating that either the producer or consumer has insufficient buffer space to translate the bound variables. Unable to establish the link. |
SNCP_ERR_BAD_CONFIG | 11 | Producer only error, indicating the producer is unable to obtain the IP address of the consumer from the network configuration file. The link is denied. |
To monitor the health of the bindings network, use the consume status variable and the following function blocks: KvbConsNetStatus and KvbProdNetStatus.
