Hello Insearch; The rules for configuring Profibus-DP slaves to a Profibus-DP network are rather standard, and you can find them in thefollowing document: http://support.automation.siemens.com/WW/view/en/18652631 Study chapter 3, Configuring the Distributed IO (DP). As you will see, DP slaves mnust be included in the Hardware Catalog of the DP master's configuration software (HWConfig, for Simatic Manager users). This is done through the use of a so-called gsd file, provided by the manuafacturer of the unit you want to insert. So you must start by searching the web (or asking the powermeters' saleman) for this gsd file for the REF 542, fot the VAMP 260 and the TQM-II (although I have a doubt this unit can be configured for Profibus-DP, GE has always provided a Modbus interface for the TQM series to my knowledge). Once you have the gsd file, you can include it in the catalog using the Tools--> Insert gsd file menu in the HWConfig. The new insertedslaves will be found in the "Other Field Devices" section of the Profibuis catalog. You must then use the HWConfig Profibus editor to setup your slaves, giveeach a Profibus address (which must match the one you provide the real slaves), configure the data areas you will use to communicate with them and the IO addresses the master will use to exchange data with them, connect to them and start talking... his is all shown in the document suggested above. Start by locating the gsd files for your slaves. When you have them, try to follow the information in the manual suggested earlier. If you have trouble, come back to the forum stating whet you have tried and what the results were. We will try to help more. Hope this helps, Daniel Chartier |

Hello Insearch; As stated earlier, providing communictaion files (if available) is the responsability of the manuafacturer; so this is a question for ABB, either to their representative or on their website. Here is what I have found on the ABB site: http://www05.abb.com/global/scot/scot229.nsf/veritydisplay/2d48af8b81a6bb56c12574c0001de98b/$file/appl_%20ref%20542plus_756405_enb.pdf Here is an extract (p. 5 and 6) REF 542plus has an embedded WEB server. In addition, the MODBUS TCP communication protocol can be used via the Ethernet RJ45 interface. An additional multi-communication system can be built using the following protocols: •MODBUS RTU RS485 (used for SPA as well) •MODBUS RTU Fiber Optic with ST connectors (used for SPA as well) •SPA Plastic Fiber version snap-in connectors •SPA Glass Fiber with SMA connectors •SPA Glass Fiber with ST connectors •COM-L (LON - LAG 1.4) •COM-I (IEC 60870-5-103) •Ethernet module for IEC 61850 The difference between the communication systems is the topology, the amount of devices, and the SCADA system of the NCC.The most common protocol is the standard MODBUS RTU (baud rate 19.2-76.8 kb/s). Connetion to a third party communication system is therefore possible. This protocol has two interfaces: optical (ST connector) and electrical (RS485). SPA is an ABB proprietary protocol, and it is also used to build communication systems. The baud rate is specified to 9600kbit/sec. SPA has a lower baud rate but it is more flexible because of different types of converters or concentrators available. The network topology can be star of loops, loop of stars, or just loop or star. The info flow speed depends on the topology and it is not strictly defined. Usually, devices are split up by sections or other primary features. |
