FX /FX /FX series PLC to realize full duplex serial data communication with another RS232C
2NC 3U 3UC
interface such as a personal computer, bar code reader, printer, etc.
1) Two or more devices with RS232C interfaces can be connected to an FX
PLC by using the RS232C special function block. Up to 8 special function block can be connected to
the FX /FX /FX
2N 3U
PLC. (Refer to section 2.1)
2) Communication requires no protocol
Full-duplex asynchronous communication between RS232C devices is specified through buffer mem-
ory (BFM). The FROM/TO instruction is used for the buffer memory.
3) The send/receive buffer can accommodate 512 bytes/256 words.
When the RS232C interlink connection mode is used, data exceeding 512 bytes/256 words can also
can be received.
4) ASCII/HEX conversion function
The function to convert and send and a hexadecimal numeric (0 to F) saved in the send data buffer as
well as the function to convert a received ASCII code into a hexadecimal numeric (0 to F) and save it
