Description
8610-FT-NA Upper computer
8610-FT-NA upper computer and more than one PLC for communication, must be connected to a RS232 / 422 level converter, RS422 using balanced transmission and reception methods, it has a long transmission distance, anti-interference ability and multi-point communication capabilities, can be connected to a maximum of 32 sets of PLCs, as shown in Figure 1, each PLC must be hanged on a COM06 unit for the RS422 Each PLC must hang a COM06 unit for RS422 connection, and the communication between all PLCs and computers adopts the PLC uplink communication protocol.
The setting switch of the RS232 / 422 converter is dialled to the 422 method, and the COM06 communication board unit on the OMRON PLC is similarly set to the 422 method and the four-wire system. The communication baud rate of the upper and lower units is set to 9600, and the data format is set to E, 7, 2.
