It is an [[ASCII]]-based protocol generally used for communication over [[RS-232]] or [[RS-422]]. The protocol enables communication between various pieces of equipment in an industrial environment for programming or controlling those pieces of equipment.<br /> The maximum allowed message size is 30 [[Word (computer architecture)|words]] per message. Larger messages can be sent by &#039;[[IP fragmentation|fragmentation]]&#039; process, where the same slave returns a series of messages to build up the entire response. PLC host computers can transfer procedures, and monitor PLC data area, and control the PLC using the HostLink protocol.<br /> <br /> ==External links==<br /> * [http://www.tri-plc.com/HostlinkE10.pdf Hostlink Command Format]<br /> <br /> ==References==<br /> {{Reflist}}<br /> <br /> {{List of automation protocols}}<br /> <br /> <br /> {{compu-network-stub}}<br /> <br /> [[Category:Industrial computing]]<br /> [[Category:Serial buses]]</div>
