CANopen Communication Module DVPCOPM-SL The corresponding relations between index H”5002>> subindex H’01 and network nodes are as follows. The corresponding bit is in off status when the nodes in the node list of master module are normal; the corresponding bit is in on status when the nodes in the node list of master module are abnormal, e.g. Initializing fails or other abnormality causes slave offline. 6.2 Master Status of CANopen Network User can read the content value for H’5003>>H’01 to acquire the master module status message of CANopen network by sending SDO.
When master module is at normal work, the content value for H’5003>>H’01 is 0; when there is any error in master module, the content value for H’5003>>H’01 is the corresponding error code.

Add slave to node list and redownload configuration to DVPCOPM-SL F2 In process of downloading configuration to DVPCOPM-SL. Wait till the configuration is finished downloading. F3 DVPCOPM-SL in error status Redownload configuration and change into a new DVPCOPM-SL if the error still exists.
F4 Bus-off is detected Check the wiring for all cables of CANopen network is proper; ensure all nodes in network are at same baud rate and finally repower DVPCOPM-SL. F5 The setting for DVPCOPM-SL node address is incorrect The DVPCOPM-SL node address should be set in the range of 1~127. F9 Low-voltage detection error Check and ensure the work power of DVPCOPM-SL is normal. FA The inner part of DVPCOPM-SL firmware is in error state. Repower DVPCOPM-SL. FB The storage space sending data in DVPCOPM-SL is full. Check and ensure bus cable connection is normal and then repower DVPCOPM-SL.
