Hi! I have my 1756 IF8 wired in high speed differential mode but i can't configure the RTS smaller than 11 ms. What I understand it should be possible to set as low as 5 ms if module filter setting is 1000 Hz. Is there anything else that i have to do? -
Connect PV 550 with DH485 to SLC 5/04 CPU with rs232
Azza posted a topic in Allen Bradley / Rockwell Automation
Hi All I am new here without much experience of plcs. I have a PV 550 with DH485 coms port that I want to replace another PV550 with rs232 that communicated with an SLC 5/04. Is there some way to connect the two with a cable or protocol connector? Alternatively can you connect through the printer port on a PV600? CHeers Azza -

Micrologix 1400 - Read more than 82 ASCII characteres
GATI_1976 posted a topic in Allen Bradley / Rockwell Automation
I have a Micrologix 1400 and one PC which sends 102 Characters in RS-232. I need to read all characters with Micrologix 1400, Is there any way to read all characters? I know the limit of ARL and ARD instruction is 82 characters. I do not know if two ARD instructions could read all characters. Do you have any experienced like that? Could you help me? Thank you in advance -
Hi 1- How can I identify a disable x20 module (in physical view) cyclically ? I am looking for a funation block who can do that because I want to use the 'Module Ok' status of x20 module to check if their presence. Problem is 'module Ok' status is the same for module missing or disable. 2- Could I disable a module using fonction block? (FYI I already know the right click in physical view). Thanks

Or if you have any otherone please share it. Please help!!! KIdoc_QD77servo_English_20130131.pdf -
In this first picture is a numerical input with a monitor device D2058. In the whole GOT project this is the only device that saves the information inputed. Then on que PLC sequence theres an instruction moving that device's value gotten from the GOT to the position module's buffer memory. My doubt comes when there's another device D10022Z9 getting the same value of D2058. In this case the Z9 index is always 0, I checked. In the whole PLC program this is the only part where the D10022Z9 appears, there is no instruction anywhere copying D2058 to D10022Z9 which is how I would think is the way it has the same data always. Am I missing something or how is this possible?

I have an omron cp1le plc and a sato s84ex printer I need to learn how to send print jobs to it. I know I can use the Serial card option and send the code to the printer over RS232. I am using the NiceLabel software and printing to file which extracts the SBL code. That is where I am stuck. What part of the code do I use and where do I put it in the CX-Programmer. And what instructions should I be learning to send Ascii to the printer. I am very new at all this and just want a few hinters and direction. Thanks.

Hi all, Quick question about adding ENET modules to a plc. If I have a local network of a HMI, PLC and 1 device all on IP 192.168.255.x and I have another device across the plant with an address of 171.27.19.x, can I add that one device to the PLC and it will recognize it? Is there a way to add a device with a totally different IP address to a PLC that is already set up?

Hello Everyone, I want to have a serial communication using Siemens S7-1200 with CM 1241 (RS-232) and communicate with my Arduino. Here is the setup of the communication. I have 2 temperature sensor and one Led connected to my Arduino, and on the PLC side I have S7-1200 from Siemens and CM-1241. Arduino and my PLC are connected just by using Tx and Rx pin no handshake is done. I am sending the temperature data from both the sensor to the PLC. on the PLC side i decide when to turn on the Led connected to my arduino depending on the different temperature values. I have assigning a ID to both the sensors before sending out the data. This is how the transmitted data from Arduino looks like $AOPT_TEMP1_20_TEMP2_21 . So far its good, I am receiving serial data on my PLC using RCV_PTP (received data are placed on the buffer) and sending data using SEND_PTP. I have also implement a filter on the PLC which will only accepts the serial data starting with '$AOPT_'. Now, I want to receive the temperature value from two temperature sensor TEMP1 & TEMP2 and then control the Led. For instance if (TEMP1>TEMP2 ) then turn ON the Led else turn OFF. I am able to receive the data on the PLC from Arduino but now I don't know how to proceed with comparing the received information. How do i extract the only required data from the received buffer? Any suggestions will be highly appreciated. Thanks in advance....

PowerFlex 753 Digital Inputs current rating
izadi posted a topic in Allen Bradley / Rockwell Automation
Hello everybody, I am connecting my DCS digital output (115VAC) to AB PowerFlex 753 Digital Input. We are using the 20-750-2262D-2R I/O option in the powerflex which is 115VAC I/O with 2 Analog In, 2 Analog Out, 6 Digital In and 2 Relay Outputs. My question is, what is the current or power consumption of the PowerFlex DIs at 115VAC. I need to specify the right fuse size for my digital output. Thanks, -
Hi All, I have problem about programming serial module Mitsubishi PLC using QJ71C24N. If I unconnect the cable from the module and connect again it show SIO error and the communication become lost or not sending data again. so i have to restart the PLC to make it normal again. Any other solution for solve this error without restart the PLC? Thanks Husanto

Hello guys, actually I am new to this Omron PLC. but i have small project to transmit a command to the GSM modem via the RS232 port so it can trigger the modem to send text msg. Can you show me the steps/guide/sample program to accomplish this program coding? I already read some topic in this forum regarding to this PLC RS232 port but still cant get the ideas when to create the ladder program. PLC Type : CJ1H (CPU65H) - RS232 port First input to trigger the GSM send text msg: AT+CMGS="+YOUR HP NUMBER" Second input to trigger GSM send text msg: YOUR TEXT MSG CONTAINS (Ctrl+z to send) Many Thanks, AlexB

Module not available even after install
HotPie posted a topic in Allen Bradley / Rockwell Automation
Hey guys. New to the forum and new to plcs. I am running into problems quick, fast and in a hurry. Please be patient. I have created a new project. I have added module 1756 ENBT because that is what I will be connected to. On the chassis there is another ether net card which runs to a switch. That switch runs to a 1734 aent card. I have added this module, 1734 aent, as well to my project. Now I must add a 1734 IB8S and a 1734 OB8S. These are not appearing in my list. I proceeded to download and install these add on profiles. After installation, however, I can still not select the I/O modules. Why is that? And how do I fix it? Thanks in advance, HotPie -
Tricky Communication in between RTU and SCADA Front End Processor
SESA218461 posted a topic in General Topics - The Lounge
I have the following situation; I have a distribution network connecting about 400 RTUs, using 101 protocol to connect to their PDH MUX, which data slot is transported using SDH STM-1/4, to the Primary Substations. Then the primary substations connect to the LDC building using STM-16. At the Control Centre Building where the Front End is located, there is a STM-16 node with some PDH ports, but definetly not 400, so how can I extract this 101 asyncronous data channels to connect them to the SCADA Front End? Note that conversion to 104 is not allowed by the client. Thanks in advance! -
Hello everybody, I'm designing a safety system for a HV power supply. The idea is to use a series of 2 contactors to supply power to the system controlled by a safety PLC. So, it is a typical application. The problem is that the power supply and the contactors are are installed on HV platform, isolated from ground, where the PLC is installed. I think the only possibility is to use an optic fiber link. Does any body know is there is any way to connect a contactor to a PLC output using an optic fiber link, without compromise the cyclical checking performed by the safety module (as I understand, the outputs are continuously check in order to detect wire breaking). The alternative that I have is to use a distributed IO system installed on the platform, connected with a Ethernet Optic Fiber to the PLC: for example using a simens S7-400 PCL with a IM467FO modules (on ground) and a ET200M system with a IM153-2FO module on the platform. But I wonder if there is something more simple and cheaper. Thanks!
