Hello, I would be grateful for some help with configuring the TCP/IP connection of the V130 controller. I have the V100-17-ET2 ethernet card in it and I did some initial attempts. So far I can see in the system bits that: SB 141 - card exists = 1 SB 142 - card initialized = 1 SB 143 - socket 0 initialized = 1 (that's the one I'm trying to use) SB 151 - ethernet status: link = 1 SB 153 - ethernet status: rate, 100 mbps = 1 For now I'm testing this right next to my PC, plugged to my home router and I'm trying to get anything to work. Right off the bat I see -
dear sir, i have 4 vessels having individual plcs model is v700, Each plc having individual festo valve (16 way digital outputs) in tcp/ip protocol, my first plc ip is 192.168.1.50 and my festo ip is 192.168.1.1 my second plc ip is 192.168.1.51 and my festo ip is 192.168.1.2 my third plc ip is 192.168.1.52 and my festo ip is 192.168.1.3 my fourth plc ip is 192.168.1.53 and my festo ip is 192.168.1.4 Question 1 : How to handshaking all plc in one loop (ex: i want to transfer my first vessel product to 2nd,3rd and 4th vessels.) regards, Mohamed -
Hi all! I have a problem with Protocol TCP/IP SCAN module. In my project I can connect this PLC (V350) with my computer through TCP/IP protocol. I use PROTOCOL TCP/IP SEND module for send information to PC and Scan module for receive it and that part work fine, with this, connection modules problems are discarded. My next step is connect the PLC with a server (same way). In this case I send a GET petition from PLC, when server receive this petition send another get petition to PLC with the valor of a variable stored in a data base, this petition must be read it by SCAN module and update -
Hi! So, I am writing ASP Core 2 project and one of the components is communicating with Unitronics V130 unit (as a Modbus Slave). Since provided .NET Driver library is not portable to ASP Core I need to implement this communication with Modbus. I have limited experience with Modbus protocols but I have used some basic functions in the past – mostly reading Registers and Coils. Just to sample some data. I used python library modbus_tk for this purpose. Using Modbus gives me options for adding more optional hardware down the line. After reviewing some libraries supporting Core I selected -

Hi all, I have hit a roadblock and am asking for guidance. I have a V350 with an Ethernet module connected to a wireless gateway (RV50). The RV50 uses Modbus (socket 2, port 502) to connect to the PLC and port forwarding to allow remote communication (socket 1, port 20256). This communication is great and has been successful for several months. My challenge begins when we want to control the outputs on a separate wireless gateway (GX450) with AT commands from this PLC by using the Protocol TCP/IP Function. The catch is that the GX450 will be in a remote destination and we will not be able -
My end goal is to send data over ethernet using the TCP/IP protocol to a raspberry pi. I already have the pi coded in python to look for a connection to its ip on a socket that I bound to it. My problem I believe is within the V570 PLC programming logic itself. I have initialized the card with ip 10.1.10.160 and my laptop with ip 10.1.10.100. Those two communicate correctly over ethernet. My pi is at ip 10.1.10.166. The pi is bound to a socket and currently waiting for something to connect to it on port 8888. I initialized socket 3 on the PLC as a Master on port 20257 and set the name to -
OK, I am stuck, and to be honest I have no idea why I am stuck. All I want to do is request a web page from a web server. Specifically, I have created a PHP page that will return the string "OK" when called. I am using this page for the PLC to report that it has an error. Inside the PHP, I will use the parameters to identify the PLC and the error. This should be easy, Right? I have configured my port and my TCP/IP configuration to socket 3, port 504. I issue a TCP/IP connect to the server (IP is correct, port is 80), and it appears to connect. I then issue a TCP/IP Send to send the GET /u

I have been tasked with developing a centralized server that will communicate with many Samba PLCs around the world. Specifically, I need to ensure that the server can contact any PLC and 1) get a copy of the current values or 2) instruct the PLC to change a value. I want to ensure that the PLCs only communicate with the server, no other computers. The data itself is not considered secret, so the fact that VisiLogic does not appear to offer encryption is not a problem. But, it is critical that only the server be allowed to update PLC values. It is simply unacceptable that another person c -
I'm trying to connect my PC with a Unitronics PLC. I would like to use Modbus over TCP/IP for this purpose. This is the first step in my project. Later on I would like to connect it to a Rabbit Wolf (BL2600) to exchange I/O. I first want to connect the Unitornics PLC to my laptop to get a decent understanding of the Modbus TCP/IP protocol used by Unitronics. At the moment I'm already stuck, so I hope that someone could help me. I did read the documentation about Modbus Application Protocol on: http://www.modbus.org/docs/Modbus_Application_Protocol_V1_1b.pdf I'm using the Unitronics exam -
Hi there, I am having some trouble reading variable length numbers in a "Protocol TCP/IP Scan" block. We are receiving a message of the form "-9999999999.999 [Counts16Bit]". Messages can be positive or negative and can contain a variable number of digits, so "9.999 [Counts16Bit]" is also a valid message. I am able to successfully use the scan block with fixed length messages. If I construct a message like "111 [Counts16Bit]0A" where the numeric variable is "Decimal ASCII: Fixed Length", Vector Length = 1, Length = 3, "No Prefix", I can receive any 3 digit number successfully. If I change
