Questions : Why it takes a long time of AR-837-E’s activation while using RS485 network?
Problem Solving :
1. Please check if controller’s DHCP function was enabled mistakenly. When DHCP is enabled, the controller will search all available IP in LAN, which greatly delay the controller’s boot time. Therefore, please disable this function as below:
Enter to the programming mode> 3. Parameters > 1.Node ID> Enable DHCPL: please select “0:No”
2. If using RS485 for network, please remove TCP/IP module (AR-837i) from the controller. When AR-837i on the controller, the controller will check the network status, which delay the controller’s boot time.
