Posted 14 Feb 2020 Once agin hello all, im pretty sure, that in the past i found in some manual special relay (SB????), that was set on when PLC was executing RIWT instruction. Now im trying to find once again, but with no luck, ive searched through all manuals that looked relevant, but nothing... any help will be highly appreciated.

Posted 15 Feb 2020 hello sczot, special link relay (SB) and register (SW) are from the cc-link master modul. If you want to use these, don't forget to setup the automatic refresh settings in the network parameter, othwerwise the releay/register are not updated! have a look at the Mitsubishi Programmable Logic Controller Training Manual (CC-Link course Q-Series) [SH-080620ENG-A] https://dl.mitsubishielectric.com/dl/fa/document/manual/school_text/sh080620eng/sh080620enga.pdf Appendix 4: CC-Link dedicated instructions (for the RIWT instruction) Appendix 3: List of special link relay/register Share this post Link to post Share on other sites
