7. Loader communications
7.1 Communication procedure
This product receives “request messages” from a high-level computer and returns “response
messages.” This product therefore does not start to transmit a message.
The timing for communications and similar matters are the same as those of TOHO and MODBUS
communications. Those depend on the way this product is set.
7.2 Message types
The configuration of messages and similar aspects are the same as in TOHO and MODBUS
communications. That depends on the way this system is set.
7.3 Cautions on loader communications
Insert the stereo jack of the loader cable all the way home (until it clicks). When using a loader
cable, either use the driver software furnished with this product or download driver software from
the website of TOHO and install it into your PC. For details, see 7.4. You should exercise caution
when making the connections for RS-485 communications and those for loader communications
simultaneously. You cannot conduct loader communications while data is communicated through
the communication line. Be sure to stop the RS-485 communications before conducting any
communication you wish to make.
