S.S.D.D. Posts: 67 Rating: (0)	Is there any worthwhile use from a SIMATIC S7 perspective to the SEAbus ethernet port on the new PAC3200 power meter? I know there is the Profi-Bus DP module to be added on for Profi-Bus communication, but I'd like to get the most out of the module as possible. The manual only really discusses the MODBUS TCP ethernet interface but what is the SEAbus TCP useful for from a process control perspective? It is nice for configuring and managing settings however. Ideally I'd like to hook this into the SICAM network but that is a different area of discussion. Thanks.

J_Bell Posts: 5822 Rating: (412)	Hello TopCat4692, as far as I understand the Product sheet at the SE&A Page this device only supports MODBUS TCP, I guess as a MODBUS TCP Slave. MODBUS TCP is also supported with the S7-300 and S7-400 as soon as you use the MODBUS TCP loadable drivers. Check this FAQ: How can you establish OPEN MODBUS / TCP communication via the CP343-1 or CP443-1 and where can you find further information? Best regards J_Bell

S.S.D.D. Posts: 67 Rating: (0)	Thanks for the feedback. I will keep the Open MODBUS option in my back pocket for a newer project but doing this would require another software license be bought and a different model CP-443 than we are using in all of our existing applications. Looks like for retrofit we might be limited to the ProfiBus option. Thanks.

J_Bell Posts: 5822 Rating: (412)	Hello, may you explain some more about the SEAbus TCP? I have never heared about it yet, you seem to know some more about it. The internet does not provide any really sufficient information, may you provide some... or someone else? Best regards J_Bell

JMJ Posts: 487 Rating: (45)	Hi J_bell Seabus is a Siemens protocol used in "Access" power product such as power meters. I think itbelongs to CD(low voltage) division.It allows power meter values to be accessed by a supervisory device and also configure the device over the bus. Seabus TCP as youimagine isthe protocol ported over to ethernet. I have used SEAbus devices withS7 PLC using Siemens SPI unitas a SEAbus to Modbus-RTU gateway. Here is excerpt from 4700 power meter seabus reference manual. __________________________________ The SEAbus protocol is an open software communications protocol for two-wire, RS-485 networks. An RS-485 network consists of a single bus supervisory device and up to 32 field devices. Short communication packets (packets) consisting of 5 to 260 characters can be sent and received at various speeds. Adding SEAbus communications to a device provides remote access to the information collected by the device. All configuration and setup procedures that are possible at the device can also be executed from a remote location over the communications link. __________________________________ http://www2.sea.siemens.com/NR/rdonlyres/22534641-F2E8-4AB6-8E13-90D3E262A9A3/0/4700_SEAbusProtocol_Reference.pdf http://www2.sea.siemens.com/Products/PowerDistribution/Product/ACCESS-Power-Monitoring/Product/Sentron+PAC3200.htm

J_Bell Posts: 5822 Rating: (412)	Hello JMJ, thank you very much for all this information... I did not find really much at the support sides of A&D. But I guess this clears a lot. Best regards J_Bell

S.S.D.D. Posts: 67 Rating: (0)	Is anyone aware if there are OPC capabilities with the PAC3200 meter? Through either SEABus or MODBUS TCP, can an OPC server or client be configured to talk to these devices? How does the Siemens power monitoring software retrieve its data (WinPM I believe??)? If I have this power meter on the process network , do not want to use the data in my CFC's but only want to pull data into WinCC, what would be the best approach? Is something like this even possible with this meter through the TCP connection? Thanks.

JMJ Posts: 487 Rating: (45)	I do not know what version of WinCC you have. WinCC 7.0 has Modbus/TCP driver inbuilt. But with any version a Modbus/TCP OPC server can be used to communicate from WinCC to PAC3200. I have not found a SEAbus OPC server. But if you find one, thatwill work too.

S.S.D.D. Posts: 67 Rating: (0)	Has anyone in this forum ever connected or tried connecting a PAC3200 directly to a Modbus TCP OPC server? I have tried several and the packages don't seem to be readable by these severs. The only thing I could get to read the packageswas a Modbus link analyzer but that is just processing byte values and displaying them. I am able to connect to the device and I have tried requesting input registers and holding registers but there are timeout errors and never good data being returned. Any thoughts? I'm not sure how often something like this is tried....
