7 / 27 page CPU Overview Programmable Controller CS1 C--17 Outstanding Connectivity and Compatibility J CS1 Offers More More serial communications ports, more protocols. Up to 34 port connections with protocol setting for each port. J Protocol Macros PLCs with Protocol Macros RS-232C RS-232C Non-OMRON PLC Non-OMRON Temperature Controller CS1 PLC Data transfer protocol for serial communications vary with the manufacturer and with devices. Differences in protocols can make communications between devices by different manufacturers very difficult, even when electrical standards are the same. OMRON’s protocol macros solve this problem by: • Enabling easy creation of protocol macros designed to match the protocol of a connected device. • Allowing you to communicate with essentially any device having an RS-232C, RS-422, or RS-485 port, without having to write a special communications program. J The Two Main Functions of Protocol Macros I/O memory Read Variable R ( ) Send Receive Variable W ( ) Write I/O memory Create Header Address Data Check code Terminator 1. Creating Communications Frames The communications frames can be easily created according to the specifications required by the con- nected device. Data from I/O memory in the CPU can be easily included as part of a communications frame to read from or write to I/O memory. CPU PMCR Port/Module Required processing Connected device Step 0 Step n (as required) 2. Creating Frame Send/Receive Procedures The required processing, including sending and receiving communications frames, can be performed one step at a time according to the results of the previous step, and then CX-Protocol can be used to trace send and receive data. J Application Examples Standard System Protocols Data transfers with OMRON components can be easily performed using standard system protocols. There is no need to develop your own protocols in this case. CS1 PLC Standard system protocol Example: E5CK Temperature Controller RS-232C OMRON component Example: E5CK User-Created Protocols Data transfers with non-OMRON components can be easily created just by defining parameters using the CX-Protocol Windows tool. CX-Protocol Creates protocols. CD-ROM CS1 PLC Non-OMRON component |
