I'm trying to spec out a system consisting of a CS1G-CPU45H CPU and I want it to be able to communicate with: 3 NS12-TS01B-V2 operator interface 1 Micro CP1L-L14DR-D with Ethernet adapter CP1W-ETN01-US Would either the CS1W-EIP21 or CS1W-ETN21 module allow me to do this on Ethernet? What I would also want to do sometimes is hookup my programming terminal and do online programming and troubleshooting at the same time. Is this possible or am I asking for too much? Thank you for any advice.

Hi, I'm just getting familiar witht the CX-Programmer software so bare with me on this. Am I correct to say that when I transfer the program to the PLC, only the logic and other configurations are downloaded but not the memory? I would have to use the PLC Memory Data Monifor to download and upload the values? Does the Data Monitor saves to and reads from the cpx file?

PCMR, thanks for your help on this project. Everything works out as designed. The WE70 wireless AP and client setup are similiar to the ones you would buy for your home so it wasn't hard to setup. No special setup like routing table and FINS. They're rugged with din rail mounting and 24VDC power so you can install them in control panels. Thanks again for your help.

I think it pretty easy to see if you're online or offline in AB's. Just curious, doens't most other major brands show their values offline? It's kind of annoying when you try to read the code offline and have to switch back and forth to the memory window to see what value an address is. Hard coding them in is not a good idea when you have hundreds of setpoints and recipes that are changeable at the HMI.

Thanks, I did see that. Would be nice to see and change the values in the ladder offline.

Thank you

I have an Ethernet/IP card CS1W- ETN21 and also a devicenet CS1W-DRM21-V1 in the same rack with a CS1G-CPU45H CPU. What I want to do is go online to the DeviceNet card via the ETN21 but can't seem to make this happen. Not sure if this is even possible. There's an Ethernet/IP network selection for going online to the CPU and that's pretty straight forward and I got it working correctly but I didn't see one for the DeviceNet software CX-Integrator (v2.33). The only way I can go online to the DeviceNet card is via Toolbus and t he serial cable.

Good catch! Sorry for the typo. It's an EIP21 and I'm using Ethernet/IP.

I have a couple 5HP VFD's in a panel with their own fuses for short circuit protection. What I want to do is over size the main circuit breaker for the entire panel instead of using 115% of the sum of the motor's FLA. Is this possible and if yes, how high can I go?

Paul, thankyou for that explamation but my question is can I oversize the panel's main disconnect breaker by say 200-300%. I want to be able to add more loads in the future.

Thanks for the explanation, Bytes. I have other inputs to consider so I guess I'll just use the drive relay output ABC and reprogram it for running status.

Can someone check what I'm doing here is correct. This is my first time with a Mitsubishi drive and Omron PLC so I am trying to get use with all the notations from the manual. I'm trying to wire the VFD running status off a Mitsubishi FR-E740-120-NA VFD to the DC input of the Omron Micro PLC CP1L-L14DR-D. It appears I have to hook up the VFD RUN terminal to one of the PLC input terminal and the VFD SE terminal to the PLC COM terminal. The control panel 24VDC power supply common is also hook up to the PLC COM terminal. Is this correct? Also I want to wire up the VFD Alarm dry contact so the panel 24VDC goes to VFD B terminal and VFD A terminal goes to the PLC input? Thank you for the help.

PMCR, I'm going to spec out the CS1W-EIP21 for this project. Also I am adding an NS8 for Micro CP1L. Do you see any problem with the CP1L interfacing with the NS8 and using SEND and RECV to talk to the CS1W-EIP21 wirelessly using the WE70? There's at most 10 words over wireless and about 40 tags with the NS8. Thanks for all the help.

Thanks again PMCR! The NS screens only communicate with the CS1.

Thank you

I'm not an expert with Omron but we have a CPMA and C200HX-CPU44 that we want to collect some data off of with our PC running Wonderware Intouch. My question is that is it possible to put these processor on Ethernet via an adapter or gateway device or will I have to run serial cable from them to the PC? Optionally, I was also thinking of upgrading them to CS1G-CPU45H so that they are similiar to our other CPU's but not sure if the program will need to be rewritten? Thanks for any input.

Thanks for the offer but I was able to talk them out of it and to stick with your original hardware suggestion thank goodness. Going back to the CSIG-CPU45H, can I add the Ethernet card on the second rack since the first one is full? If not, since the 1st rack is an 8 slot rack, I can upgrade to a 10 slot without too much trouble but will there be any programming issues I should expect?

PMCR, do you think I can add a third NS touchscreen the CP1W-ETN01-US so basically 2 NS on the CP1W-CIF41 and 1 NS plus the WW on the CP1W-ETN01-US. The problem is the PLC is in a remote location and we need to control the equipement at multiple locations. Maybe best to go with a bigger PLC platform?

Thanks for the explanation, PMCR. Glad to know there's 2 different cards because the web only listed the CP1W-CIF41.

That's great! I was reading the Ethernet spec a little more and was a little concern if I will be able to connect 2 NS12 terminals as well as the Wonderware Intouch. The specs says only 2 simutaneous connections? I'm looking to pull probably 100 - 150 tags from the PLC for each touchscreen and around 30 tags for the Wonderware. FINS Communications Service Specifications Number of nodes 254 Message length 1016 bytes max. Size of buffer 8k Communications Function FINS Communications Service (UDP/IP, TCP/IP) FINS/UDP method Protocol used UDP/IP Port number 9600 (default) Can be changed. Protection No FINS/TCP method Protocol used TCP/IP Number of connections Up to 2 simultaneous connections and only one connection can be set to client Port number 9600 (default) Can be changed. Protection Yes (Specification of client IP addresses when unit is used as a server)

Ok, thanks. Now going back to the CP1L CPU, does it have a built in serial port or is this something I need to order extra along with the Ethernet port?

Thanks for the info, PdL! I was also looking at some of the programming terminals like the NT31 and NV series but they don't appear to support Ethernet. Is this correct?

Thanks for all the hardware suggestions. I will definitely check them out. If anyone is interested in the Digi, it's actually the IAP, not the IA model that works with Omron. For the software portion, Kepware says their Host Link OPC driver will support the CPMA under the "Open" option but I'll try the ww free driver Scott suggested. If I was to upgrade the CPMA, what is the most cost effective Omrom model with Ethernet? I don't need more than 10 discrete IO's and if I can get a few analog inputs, that will be a plus.

Scott, We are using Intouch 10.0 and WW Omron FINS Ethernet DAServer 1.5 to connect to a couple CS1G-CPU45H. WW also has the Omron FINS Serial DAServer 1.5 but it wont work with the CPMA so I was looking for 3rd party drivers. The OMRONHL8 sounds like an older style driver from WW? Is the Omron's Hostlink Protocol sold by Kepware. I didn't find any support for the CPMA on that one if it is. Also I've found some info on a serial to Ethernet converter (Omron Digi One IA) but reading further it's a modbus to modbus/TCP converter so I am a little confuse if it will work for the CPMA and C200HX. The first link says it does and the 2nd says it's modbus. I'm guessing the serial protocol for CPMA and C200HX is modbus? http://www.digi.com/support/kbase/kbaseresultdetl.jsp?id=489 http://www.digi.com/products/serialservers...ia.jsp#overview

Thanks for the suggestions, Scott. Do you know what serial protocol is use by the CPM2A and C200HX-CPU44? I guess my next step is to find a DDE or OPC IO server. Update: Ok so I did a little poking around and there's plenty of OPC servers for the C200HX from well know companies but not for the CPM2A. Any recommendations? I would like a server that can handle both rather than buying separate packages. I read up on the Omron CX-Server OPC and believe this will work with both PLC's?
