Tricky Communication in between RTU and SCADA Front End Processor
SESA218461 posted a topic in General Topics - The Lounge
I have the following situation; I have a distribution network connecting about 400 RTUs, using 101 protocol to connect to their PDH MUX, which data slot is transported using SDH STM-1/4, to the Primary Substations. Then the primary substations connect to the LDC building using STM-16. At the Control Centre Building where the Front End is located, there is a STM-16 node with some PDH ports, but definetly not 400, so how can I extract this 101 asyncronous data channels to connect them to the SCADA Front End? Note that conversion to 104 is not allowed by the client. Thanks in advance! -
Trying to add points to a QLC link from WDPF to SLC5/04, incorporating a 1770-KF2 DH+ interface module. This link has been in place for years, incorporating only DCS reads (both digital and analog). We recently added several more DCS reads successfully, but cannot seem to get digital or analog DCS writes to be seen by the registers in the SLC5/04 data table. Could this be a limitation by the 1770-KF2 module, or is there a more probable reason? SLC5/04 DH+---------1770-KF2---------QLC Could Duplex settings on the 1770-KF2 module have a bearing on this dysfunction? Successful DCS analog reads PT101, N9:2, A0000 PT102, N9:3, A0002 DP103, N9:4, A0004 Unsuccessful DCS analog writes PV101, N9:18, A0500 PV102, N9:19, A0502 PV103, N9:20, A0504 Any insight would be greatly appreciated. Thanks.

I would like to combine two existing machines with CC-Link. Each machine has a QJ61BT11N set up as its Master Station. The larger machine has 26 remote I/O and 4 remote devices. The smaller machine has 1 remote device (see the attachment). Each are already programmed and running. The larger machine has HMIs that I would like add screens to in order to control the smaller machine as well. The smaller machine would basically just need to send and receive a handful of signals... start, stop, manual, origin, e-stop, fire specific outputs, etc. What would be the best way(s) or simplest way(s) to connect and communicate between these machines? I am open to any advice and ideas. Thank you Machine_Addition_Via_CCLINK.bmp

Hello, can someone recommend HMI's which can be connected to my cc-link network? or is it better to use a PLC on the cc-link network and attach the HMI to the PLC? I just find the GT16 very expensive and I believe they need CC-link IE? Thanks you.

Good day pals! Can I ask something about the CC-Link Network? I have a concern regarding cross-communicating two CC-Link Masters using MC Works Master PC. Can you guys help me with the system architecture? Thank you very much. Your help will be greatly appreciated pals. Thanks a lot.
