Hello a.z.r.; The best docuent for SFBs and SFCs is this one: SIMATIC System Software for S7-300/400 System and Standard Functions - Volume ½ https://support.industry.siemens.com/cs/us/en/view/109751826 The extract below shows that with exchanges between S7-400 PLCs the minimum guarantied amount of data per ADDR_x is 400 bytes; the maximum data exchange sixe per ADDR_x parameter is presented in table 2. Hope this helps, Daniel Chartier |
