You can move the jumpers inside the V130 to put Port 1 into RS-232 mode. You can put the PLC into STOP mode using Info Mode to get it to stay in PCOM protocol. Modbus isn't initiated until the first scan of the ladder program. If you Check Connection from Visilogic and get a response then you are configured correctly. I suspect you still won't be able to upload the program unless the original programmer did a Burn Upload project. It is disabled by default. Joe T. -
Hello! I'm working with a V130-33-B1 with an existing program runing inside it. I try to Upload the program to my PC but I cant since it has RS485 MODBus Prtcl pre defined by someone else. The PLC has 2 ports. Port 1 (RJ11) seems to be the connection where to program with PC as usual. Nothing connected. Port 2 (RJ11) same side of port 1, it's connected to circuit board of I/O since model B1 has no I/O in it. When I check the (i) button>info mode>communication>1.Serial both ports has this config: COM - RS485 Prtcl: MODBus Ign Brk:N Settings: 115200,8,n,1,N Tx/Rx: 0000 0002 Silence: 1,25 Since this is RS485 I can't use regular RS232 cable (mine is RJ11 to DB9 4 wires made by myself to USB converter HL340). This is obvius but i'm new to this config so I clarify it. I tested some RS232 programing process with another V130 of mine using my custom DIY rj11toDb9 cable and works perfect. My problem starts when I try to retrieve the program of the controller V130-33-B1, as I said, with 2 ports (Port 1 and 2) in RS485 Modbus protocol. I connected to port 1 since port 2 is directly connected to another I/O circuit. When connecting to port 1 I used my cable RJ11 to DB9 to USB converter HL340 and then in Visilogic I try Connections>Communication & OS to Get OPLC information via serial. Here I got the error 206 message related to communication problems wich don't let me Upload the program from the PLC to my PC. I obviusly think is the RS485 thing. The question is: I need to get a RS485 cable or converter to connect to the controller? (this is obvius but I need to read it from someone). Can someone explain to me the circuit if i can make it myself. I already has a RS485 TO RS232 Converter (showed in picture) model 485SD9TB. If so, how can I retrieve the controller's program into visilogic if the comunication protocol is modbus? As I read in other forums, this may cause problems with COM and PCOM trying to comunicate with modbus device and ignoring the programing of my PC. What's the steps of getting the controller program with Upload whit this configuration of the controller, I'm really new in Modbus 485 configs and really want to understand what is happening to debelop more embebed circuits. I don't know if I can just move the internal jumpers of the controller to be in 485, but I don't think so since it has a program that expect 485. Thanks very much, I try to explain my situation the best as I can. If u have any question please let me know.

there are different ways of doing this..... 1. if you are over the 200 psi, then you can reset the action that you have declared 2. you can hide the button using a bit -> if psi <200 then set bit -> and use this bit as view the button (tag : visibility in properties window of button) 3. if you want to show always the button, then you copy the button and paste it on the same place but with no action underneath. Then according the psi you show button with action or button without action... -

I use version 1.33.236. Is Zone_Ctrl UDFB called continuously? Otherwise, the error makes sense because local tags are created only when the function is called. -

Hi Saragani, similar to the Within range, but the opposite way, it is possible with 2 tools, but I feel it would be a nice addition, I Personally would use it a lot I would also like to suggest being able to add more than the default 8 layers in the HMI screen builder, sometimes when I have multiple custom controls for example, I would like to be able to hide them 1 at a time, if there were capacity to add layers to suit your needs this would be helpfu Lastly, support for SVG images would be very beneficial,
