楼主
我使用concept2.6与plc连接后,在线监测变量的时死机并出现如下报警:
Concept caused a general protection fault in module GLC318W.DLL.
关闭concept,启动连接时出现报警: Unknown modbus Programming exception code.
再连接出现:Control is already logged-in to another programming panel;继续连接都是Control is already logged-in to another programming panel.
ping 地址都是通的
想把程序上传,在任意一台上位机用concept空程序与plc相连还出现Control is already logged-in to another programming panel.
热插拔NOE或对plc断电均会使人机界面与plc也失去连接,连地址都ping不通,会影响生产(之前已经用过).
请高手指点!
