After getting my logic to work. I went in and implemented the logic with my plc. It worked but in order for me to test part 2 of it, I have to turn the machine off and turn it back on as part of a reset feature. When I turn the machine back on, it wipes out my logic and goes back to its default logic. It's almost like I never changed anything. I connected my pc to the plc and connected to plc, pulled up the code and ran it on "Online Mode" where i can make changes and send them to the plc and yet again it wipes out whatever changes I had made and goes back to its default. Any suggestions?

Help understanding old Sysmac C20
Hi,
I have taken over maintaining some HVAC units that are run by the Sysmac C20 PLC.
To keep a stock of PLCs handy we have had to buy used PLCs from Ebay.
The current PLCs are fitted with ROMs that I presume contain the ladder code in them. I have managed to just fit the OS and data ROMs into these 'new' PLCs and about 45% of the time they work.
To try to work out how it all works, I removed the ROM and cleared the RAM contents, using the programming module, so that I can write some basic testing code to test the PLCs and make sure the relays are good in the 'new' PLCs.
After playing around I cleared the RAM again, then replaced the original code ROM and set the DIP switches to the ROM setting. On switch on, the unit does not appear to be working, checking the code using the programming module I see no code.
To try and figure out whats going on, I removed the ROM from a working PLC and the unit still works, which I guess means the code is running in RAM.
I had assumed that setting the DIP switches would make the code run from ROM. Or at least copy the code into RAM.
Is there some action I need to do to get the ROM code copied into RAM?
The manual doesn't really expand on using ROMs.
All it talks about is saving/loading the code from tape, which I dont have, just ROMs.
I am trying to get the Host link adapter, as using the load/save method seems to be very hit and miss, mostly miss.
I appreciate any help or suggestions.
Thanks.
The plan is to eventually replace these with a newer PLC, but for the time being I have to keep these going.

CJ1M to Movicon Interface from Message
Hi,
Im starting a project to interface a PLC function system and im still confuse about what protocole to choose to communicate (CJ1M CPU13) with Movicon interface by the way i have three PLCs with ETN and the others just the RS232C . The project is to interconnect 11 PLCs ( CJ1M CPU13) with a HMI in order to see the working process of the PLCs .
I could use your help solving my problem.

NT20S-ST121 - Permission Denied message
All,
I have a customer asking me about a problem on their Omron screen. I'm sure that it is nothing to do with our programme on it more that they are trying to do something with the screen or even CPU outside of our programmes.
The full message line I can see from the screen shot is:
Date/time stamp (at start), HddBcupExec,Level???,Err=70, Permission denied
The ??? are characters that I can not make out
I have no knowledge of these but even to my untrained eye I guess that Hdd bit is essentially Hard Disk Drive, so they are trying to write to the disk?
Customer reports " the fault was generated on panel first time yesterday and today too on first morning when turn-on the machine"
Any help greatly appreciated.

Error on connecting to plc
Hello,
First thing, I'm new over here, so probably I don't know everything, and second thing, sorry if my English is worse than I think :(
Now, what's the problem: I have CQM1H - CPU51 plc, and until yesterday it worked fine. But when I tried to look into its communication protocols via cx-protocol, something went wrong as I suppose. Since that, I'm unable to connect to plc - usually message is "Failed to connect, check following:..." or sometimes "No response from plc" (which probably means that there is connection if pc can send data to plc?). LED "comm" on plc is not blinking when I'm trying to connect, so it looks... not good for me. I tried using rs232 port in cpu unit, on serial communications board, only peripheral left, because I don't have matching cable. Anybody knows how to make communication work again?

cp1l to cp1l modbus easy slave ?
Are you able to do modbus master slave comms between plc's ?
Is there a modbus easy slave function block available?
I have a developed a program that talks to several drives via modbus using the easy master function blocks but I want to be able to talk to a slave plc using modbus over the same link if possible.
I'm upgrading a system that uses hostlink to a slave plc and digital I/O to interface several VSD's from the master plc.
The original system lacks I/O so using modbus to interface the drives reduces the I/O and still maintain a same size plc fitting within the same cabinet.
I'm trying to avoid going to a cp1l-m plc and having a modbus and host link network.

URGENT !!!!!: Controling several PLCs with a single PC
Hi PLC community,
i'm working on a project with Omron PLC CJ1M CPU 12, my topic is to control 5 PLCs (CJ1M CPU 12) with one PC .
the current state is :- each PLC is controled with one PC , and each one of them order an automatic insertion machine.
- each machine contains a proximity sensor ( BALOGH) that detecte the reference of the PCB( metalic card)
there is a sort of communication between the PC , the PLC and the proximity sensor :
from what i understood already , the proximity sensor detecte the reference of the metalic card , which is connected with the omron PLC (CJ1M CPU 12) , and finally there is a serial connection between the PC and the PLC that circulate the information given by the proximity sensor , the PC contain an application ( i don't have the source code) that compare the information given by the plc via serial connection and charge the suitable coordinates in the PLC in order to place the electronic component in correct place.
this instructions done by each PC that control his PLC.
any solution to generalize the work done by 5 PCs , with one and only PC ??
Hope it's all clair and have a response as soon as possible .
Regards.

Connecting 4 PLCS to One PC and CX-supervisor
Hello,
Thank you for giving me the opportunity to join your awesome community. I am pretty much a beginner in using more than one PLC so please bare with me. This is my problem so far,
I have four C1JM PLCS with no Ethernet port built into them BUT I also have four serial to Ethernet converters (MOXA NPORT 5110) and a switch. I want to make a small control room so that I can control all of the PLCS from a single PC using CX-Supervisor. My problem is that i don't know how to make a network between the four PLCS and the PC and how to configure them on CX-Programmer and CX-Supervisor so that i can control all the four PLCS from one PC.
Your help will be much appreciated. Thank you in advance and have a nice day :)

i have OMRON CJ1M CPU with SCU41-V1 CARD for RS-422/485 communication with omron inverter of model V7 via PMCR(260) Instruction. now i want to replace the V7 inverter with V1000. i have made all the port settings and parameter settings for V1000. but i am not much familiar with cx-protocall. i wnat to edit the send and receive sequence for V1000. i have the sequece as mentioned below for V7 inverter. please can some one help me on this regard.
send message for v7 inverter was written as mentioned below.
send msg:
SD(0)_1 <a>+[100118000102]+(R(2),2)+<c>
SD(1)_1 <a>+[0300230001]+<C>
RECEIVE MSG:
RV(17)_1 <A>[0302]+(W((1),2)+<C>
i could not understand the data part [100118000102] as i know 118 is the register for frequency reference 1(master freq) for v7 inverter. please help me to re-write the above send and received message format for v1000 inverter.
thanks and best regards,

Hello there. I need to download the application from a Omron C20H plc and have already tried with severeal cables, but had no success. Is it possible to do it with a simple hand made cable, or i need to use this intergace 3g2a6-lk201-ev1? I read somewhere that i could comunicate with C20H with a simple cable. By the way, with hand made one i did receive some errors, but now i do not have here the printscreens that i made. later i will put them here and i hope that somebody wil help me. regards From pT tintin2005

CJ2M do not need to this setting ?
I/O Devices Form
Complete the I/O Devices form as instructed, with the following specific information.
I/O Device Address
The station address for an Omron CV Series PC is specified as follows :
w/n/u/V for CV mode
or
w/n/u/S for CS1 mode
where
w is the FINS network address (1-127)
n is the FINS node number (1-126)
u is the FINS unit address (0)
There are no defaults for w, n, or u, but if you do not specify a mode (with a V or S), it will default to CV mode.
The FINS node number should be the same as the IP address node number. The FINS network number should be the same for all ETNs on the Ethernet segment.
There is no relationship between FINS network numbers and IP network numbers.
Thank you..

MOVE
Hello all,
I am sorry in advance for asking such a noob question.
I have a few Ethernet/IP stepper drives that I am controlling using nX1P2. Now, I am trying to execute 3 motions sequentially. It's not working. I have the logic attached in the pic.
My idea was to use a ZoneCompare and when the motor is in that position it has to execute the next move.
Any ideas why it's no working?
Thank you a lot
