Hi all, Thanks Pandiani for starting this post and I have similar questions. From the IM modules document, I have questions regarding the IM153-4 PN interface module and analog cards. I understand from reading the ET200 manual (https://cache.industry.siemens.com/dl/files/798/1142798/att_859626/v1/et200M_operating_instructions_en-US_en-US.pdf?download=true), you can install up to 12 modules and there's a maximum address space of 200 bytes. If I wanted to fill the rack with analog cards, say with a 8x13bit analog input card. Does that mean I'm going to be using 8 x 13 x 12 / 8 = 156 bytes? Meanwhile using a 16bit card would then use up 192 bytes. My concern is if there are any issues with scan time or data exchange between an interface module and PLC (say S7-400) if we were to fill a rack full of analog cards. Thanks in advance! ------------------------------------------------------------------------------------------ |
