  1. Connecting AB SLC 5/03 with Siemens HMI

    What you are trying to do is indeed possible. In WinCC Flexible (I am assume you are using it for the MP277), you can select AB DF1 (RS422) or AB DH485 (RS485). For DF1 you will need a converter, but that can introduce its own problems from experience with AB DF1. As long as Ch1 on the SLC can be configured for DH485 (which it is from memory) then go the AB DH485 option. Either way, make sure that the Channel setup on the CPU matches exactly the communication settings in the MP277 communications setup. Specifically, baud rate, parity, data bits, stop bits and the one that is easy to overlook but also critical Checksum. The default checksum on the AB CPU is normally different to the default in the MP comms setup. Also, if using DH485, in the control panel of the MP277 there is a specific icon called DH485 where you need to make appropriate settings. Of course there is also the dip switch settings for IF1B to switch between Profibus and RS422/485. From my experience, it has normally been the setup of the CPU channel incorrectly that has caused most problems. Hoep that give you some things to look at.
  2. B&R X20 to Proface HMI

    It is indeed possible, but definately not the most straight forward or least time intensive. For the most straight forward and simplest HMI setup, use a B&R power panel as terminal to controller. All the program, tags and HMI config is in AS. So neat and integrated and quick to set up. However if the 3rd party HMI is your only solution, you need to decide which communication protocol to use. Once you have that sorted and then the subsequent hardware interface (either onboard of via pluggable IF module or CS module) you can then write code or use FBKs or use onboard OS comms. For example, 1. Setup the Ethernet port (not EPL) to be a modbus TCP master -> set the HMI to Modbus TCP slave 2. Use FBKs for Modbus RTU/ASCII Slave/Master with FBKs to onboard RS232 or pluggable CS or IF module -> respective Modbus RTU/ASCII Master/Slave at HMI 3. Use FBKs for other serial protocols (e.g. DF1) on CPU -> set HMI to a DF1 protocol 4. Use FBKs for E/IP on CPU -> E/IP on HMI 5. Profibus DP Master or slave IF module - > Profibus DP Slave of Master HMI 6. CAN Open via IF module -> Can Open with HMI As far as EPL is concerned, I am not aware that Proface offers an EPL interface and driver
  3. B&R 2003 CPU 470

    It is not possible to upload the source file. You can upload the compiled files, but you cannot look at the contents within AS
  4. Interchange Data s7-300 to Compactlogix

    If you want to have a data gateway, a PC running Kepware OPC Server and Linkmaster does work nicely. I completed a project recently transferring data from a S7-300 to multiple SLC500, PLC5 and Logix processors with the Kepware SW running on an embedded Industrial PC box. The PC will require an physical interface that is available on the S7-300 PLC (Ethernet, Profibus, MPI). However if it is just a single connection between 2 PLCs that you mentioned, it might be a more cost effective solution to put a 3rd party card in the CompactLogix and then communicate directly to the S7-300. For example Profibus-DP scanner and then a DP/DP coupler. OR Generic UDP Card then send/receive data to S7-300 with CP343-1
  5. Siemens Wireless LAN problem

    Bus Fault indicated that the interface module does not receive initialisation from Master system OR initialised but commuincation lost 1. Check that the radio link if functioning (and there are many things to get wrong there) and fast enough as well. 2. Check IO config is correct 3. Look at CPU diagnostics buffer if S7-300/400
  6. recipe management WinCC flexible

    If I understand your question correctly, the only way to have a fixed text lookup is to incorporate a text list into the data record entry. Then a number can correspond to a text entry that can either be displayed in the recipe control itself or if needed elsewhere via a tag and seperate text list object.
  7. Protool / Protool Pro

    your local SIemens office or distributor should be able to cut you a copy of the original CD providing you have the license documents. EVen though the product is now obselete, if you do misplace the authorisation, that can still be re-instated via the hotline centres provided you have the license documents.
  8. Siemens S7 engineer

    As already mentioned there are heaps of resources available. But experience in real world projects is probably the best thing to become competent. There are many many people that know S7, but most commonly from my experience, just the basics. When you can proficiently and effectively use and implement all the S7 basic and higher level languages (LAD, STL, FBD, SCL, Graph, Hi-Graph) as well as PDIAG as well as the HMIs (WinCC Flex & WinCC) with their numerous options (like ProAgent) then you become a power S7 engineer. This typically takes a couple of years once again in real projects. And now of course there is the new TIA portal software. Fortunately it is not a brave new world, but a new UI.
  9. B&R Automation Studio -- how to run a project?

    How your perform a simulation depends on your version of Automation Studio. If V3 + then to simulate your real world controller, it is a straight forward process of: 1. adding a AR000 controller into your configuration view 2. Adding the relevant logical modules to the physical view of the simulator config 3. Start AR000 (from Tools menu) 3. Going online (an AR000 TCPIP connection needs to be configured) 4. Download config 5. test If you also have a HMI your need to simulate, you need to configure a VNC viewer on the virtual IF of AR000 and then using VNC viewer you can simulate your HMi as well. Works really nice and easy to swap between real and simulated worlds. If using AS 2, then you need to copy objects between 2 projects (1 for real HW, 1 for simulated HW). So a little more work but still possible. BTW, the simulator is SG4 based, so if using SGC or SG3 controllers, be careful, as some libraries etc will not work without manual adaption to the different target.
  10. Siemens MP277 to CLX via Profibus

    MP277 to CLX via Profibus is not possible. However MP277 to CLX via Ethernet/IP is. Works like a charm and easy to setup in WinCC Flexible. FYI. For Profibus (even to Siemens S7), to retain high level HMI functions the MP277 uses S7-Protocol as application layer.
