BCC Enable or Disable
Priority Low
- MICRO/I type performs communication based on 3964 (R) and RK512 protocol.
- CP340 is supporting only the 3964 and 3964R protocol. Therefore when using CP340, it is necessary to construct the pro-
gram to realize RK512 protocol in PLC. This is programmed using the function blocks FB2 and FB3, in SIEMENS PLC.
- CP341 is supporting 3964 (R) and RK512 protocol, please choose RK512 by setup PLC.
- The program of CP340 refers to a sample program.
The sample program is recorded on CD-ROM after Wind O/I NV2 Ver2.50.
Please refer to the following folder.
(Wind O/I NV2 CD-ROM) /Sample/Host_if/SIEMENS/ Downloading from our Web site is possible.
