I140:
Communication instruction RS (COM1 RS-232) can be designated to send interrupt request
when specific charcters are received. Interrupt I140 and specific characters is set to low byte of
D1167.
This function can be adopted when the PLC receives data of different length during the
communication. Set up the specific end word in D1167 and write the interruption subroutine
I140. When PLC receives the end word, the program will execute I140.
I150:
Communication instruction RS (COM2 RS-485) can be designated to send interrupt request
when specific charcters are received. Interrupt I150 and specific characters is set to low byte of
D1168.
This function can be adopted when the PLC receives data of different length during the
communication. Set up the specific end word in D1168 and write the interruption subroutine
I150. When PLC receives the end word, the program will execute I150..
I160:
Communication instruction RS (COM3 RS-485) can be designated to send interrupt request
when specific charcters are received. Interrupt I160 and specific characters is set to low byte of
D1169
This function can be adopted when the PLC receives data of different length during the
communication. Set up the specific end word in D1169 and write the interruption subroutine
I160. When PLC receives the end word, the program will execute I160
