DeviceNet Network Scanner DVPDNET-SL 7 Display of Node Status on Network 7.1 Display of Node Status in Scan List This function is to monitor if DeviceNet slave is offline or not. DVPDNET-SL does read-time monitoring to the nodes in the scan list and maps the status of every node to a bit. You can acquire the node status by monitoring D6032 ~ D6035. See the table below for the corresponding relation between PLC devices and the nodes on the network: When the node in the scan list is normal, the corresponding bit will be off. If the node occurs with abnormality, its corresponding bit will be On. 7.2 Status of DVPDNET-SL You can acquire the real-time status of DVPDNET-SL by monitoring D6036.
When DVPDNET-SL runs normally, D6036 = 0. When DVPDNET-SL is being initialized, the high byte of D6036 = 1 and the low byte = 0. When error occurs in DVPDNET-SL, the high byte of D6036 = 2. For detailed error information, please refer to the error codes, i.e. the low byte of D6036.
