Hi all, Quick question about adding ENET modules to a plc. If I have a local network of a HMI, PLC and 1 device all on IP 192.168.255.x and I have another device across the plant with an address of 171.27.19.x, can I add that one device to the PLC and it will recognize it? Is there a way to add a device with a totally different IP address to a PLC that is already set up?

Hello everyone, I need to modify furnace ladder diagram to take control of the upper PID limit. The temperature on the furnace is controlled using PID. There is master PLC CJ1GCPU45SP which communicates several slaves CJ1MCPU13. It looks that all the PID parameters are send from the master to slaves over DeviceNet using seven DRM21 modules installed on extension rack. I can see where the values for the PID are entered on the HMI and moved to new location in the master but I don't understand why they are not placed in memory locations used by DeviceNet by default as per DRM-21 manual ( which if I understand correctly are D30000 to D31599). Is it because the DRM21 are mounted on extension rack? I will list all the upper limit locations in master, it is a long list but hopefully will help in resolving this issue: HMI entry location Moved to location in the ladder D16401 __________________ D32023 D16403 __________________ D32047 D16405 __________________ D32071 D16407 __________________ D32095 D16409 __________________ D32323 D16411 __________________ D32347 D16413 __________________ D32371 D16415 __________________ D32395 D16417 __________________ D32623 D16419 __________________ D32647 D16421 __________________ D32671 D16423 __________________ D32695 D16425 __________________ D29923 D16427 __________________ D29947 D16428 __________________ D31723 D16429 __________________ D31756 D16430 __________________ D31757 D16431 __________________ D31758 After they are moved to the D3xxxx location they are not used anymore anywhere in the master PLC so I am assuming they are transmitted over to be used in slaves. Is my reasoning correct? How can I calculate address space used by each DRM-21 card to make sure I am understanding what is transferred where? Thank you.

Hello all, I'm new to this forum, hope I will be able to get some answers on this forum. I'm wotking on maintanance for machines under productiona and I would like to conect one machine to my work PC. But when I try to setup conection with RSLinx, RSLinx don't see my PLC. Problem is that my PC is on network with IP addresses 192.168.8.XXX and machine is on 192.168.0.1 IP address and between is cisco RV180 routher which is set to have LAN address 192.168.8.168 (company network), and WAN is set as 192.168.0.200 (subnet 255.255.255.0, gateway 192.168.0.201, dns 192.168.0.202). When I conect directly 1756 ENBT/A card to my laptop (laptop is set to same range of IP addresses) I can see PLC and everything is working but this way is not practical for me. Is there any way to conect my office PC to PLC, some settings in RSLinx Clasic? Any idea would be helpful. I attached simplified network drawing for easyer understanding. network.pdf Thank you for your time and help, best regards, baric1007

I have a Simatic S7-1200 and i have a couple of questions :) I have three analog sensor giving information to the plc. software = Simatic step 7 basic V11 my questions: - can i connect the plc via a cable to a rooter to access the network to use a printer ? -can i connect a SIMATIC HMI KTP400 BASIC COLOR PN via a cable to a rooter to use with the plc via the network? - can i generate a document in the software , add my sensor data and print the document using all of the above ? thanks for all the help :)

Is possible to comunicate an Eaton/Cutler Hammer INCOM/IMPACC network with a Modbus network ? Any experience ? Many thanks in advance.

hello navigators anyone has ever tried with cx simulator to simulate the network with eternet query from another external PC turns to where cx simulator?
