Ola Everyone. I have a problem and hope somebody can assist me. We have an ancient MELSEC-K2N PLC which we need to replace it with OMRON CS1 PLC. Anyway I’m new in both the brands and facing a problem with one instruction which is the Temporary Memory Shift (SFT) I’m just having a problem understanding the SFT instruction section in the MELSEC programming manual. This is the part in the manual which explains the SFT instruction and below is one part of the ladder diagram in our existing program which SFT instruction is used, can anybody let me know which shift instructions in OMRON software would exactly do the same function. This is part of our ladder program Thank you.

Andy Sergei Hey thanks guys, I really appreciate it. Let me go back to the instructions manual , and I'll let you guys know what happened. Thanks again. PEACE

Thanks a lot Sergei You've been a great help BUT can you please explain the MC/MCR again I can't seem to find this in the instructions manual (I mean MC/MCR instructures), do you mean the JMP will do the same function without the control contact on the vertical ladder bus? What if the contact (bit) that activates the JMP (004) is deactivated (false) befor the section program is executed between the JMP(004) and JME(005) will that bypass the section of the program or it will be executed normally untill it is reached the JME(005) instruction and it is reseted? Thanks again

Regards to everybody, I’m replacing an old Mitsubishi PLC with CS1D PLC and I would like to make sure which instructions can I use to replace the following instructions without having to change the whole ladder diagram. 1 2 3 1- For the MC & MCR do I just use a normal SET/RESET internal relay and use it's contact or is there another solution? 2- For SFT do I use the WORD SHIFT? 3- For the PLS do I use the DIFU?

Thank you for the help Veganic

Anybody please Can somebody tell me where can I download a programming manual for Melsec K2N PLC? Thank you.

I'm using a C200HW-PRT21 Profibus slave unit with CS1G/H PLC, but when I try to assign the unit in the PLC I/O table on the CX Programmer, I can’t find the C200HW-PRT21 in the communications adapter list only the Profibus master unit is available. Can somebody please tell me how I can assign this unit in my I/O list?

Hi all, does anybody know where I can find a freelance programmer for Omron PLC used in our project here in Kuwait? Thanks.
