Hello, I'm working on a project that involves using a 1734-AENT remote IO module. In this project, I need to configure analog inputs, digital inputs, and digital outputs. Since I'm new to this field and have limited experience, I'm looking for guidance in creating a wiring diagram. If anyone in this community can provide assistance or perhaps share a basic wiring diagram template, I would greatly appreciate it. My primary focus is on generating the wiring diagram itself. Thank you for any help you can offer.

CompactLogix power supply distance
Sergei Troizky posted a topic in Allen Bradley / Rockwell Automation
The 1769-SG001 manual says: "Check the specification table of each module for the power supply distance rating. This rating indicates how many slot positions the module can be from the power supply." The CPU power supply distance rating is "4 modules". Does this mean 4 modules are allowed between the CPU and power supply? Or the CPU to be maximum the 4th slot from the power supply? -
Good day sirs, i would like to see your help with this our company owns multiple HMI Omron NS8 it seems that this unit always break in the site. we fixed one of the unit but it is only showing white screen is this possible that there no CF connected inside the HMI?

Hi guys! I need some help with a powerflex 525 multi speed configuring. I know I have to set the P046 parameter for 2 “DigIn TrmBlk” (source) and P047 parameter for 7 which means present frequency. This is the speed reference. I need 3 speed, so I will use Terminal 5 and Terminal 6. When both terminal is zero then 10 Hz, when terminal 5 is 1 but terminal 6 is 0 then 20 Hz and lastly if both terminal is 1 then it will be 30 Hz. I will adjust the speed with the parameters: A410, A411 and A412. Terminal 2 would be the forward and terminal 3 would be the reverse direction. I think these two can be two PLC digital output trough one-one relay. It will be counted the distance by an encoder. When it reach the target the run command will be released and the motor will be stopped with the decel time1. Also I will connect the S1 and S2 for safety. My question is do I have to connect other wires ? Also do I have to remove the jumper between terminal 11 and 1 ? Am I forget something ? Any comment would be highly appreciated. Thanks ahead.

According to picture 1, ''Piston A moves to the right. After the set time, K = 4, the normally closed timer T450 contacts open and the normally open timer T450 contacts close.'' But according to picture 2 After the power flow from Left power rail to right power rail, it should directly go to 2nd rung and cause the normally open timer T450 contacts to close only right? but why it will go back 1st rung and cause the normally closed timer T450 contacts to open? Anybody can help explain me regarding this. Thank You in advance

We have been having a re-occurring issue where some of our PLC's throughout our plant have a network outage that occurs around the same time every night. The PLC's are disbursed among the plant and it has been confirmed no large pieces of equipment are being turned on around this time every night... The network traffic does not fluctuate around this time and is not near a "troubling" level. There was a reboot to one of our servers on the same VLAN as the PLC's that are having the connectivity issues... What could have changed from a server reboot to remedy this issue, the server is not communicating to the PLC's, they are just on the same VLAN.

Has anyone had any issues with dirty power or disturbances from Utility that occur duration the night?

How to konw what type of ladder programming language is support by the plc compnay
forbidden_masud posted a topic in Other PLCs
Hey there, I have an "Italian safe CNG dispenser pm head". I googled about it and found that It is a plc board. So I searched how to program it. Then found it use ladder programming language. Now there are no tutorial or documentation about its programming. But I want to repair my damaged plc board. If I goto any technician they will charge a huge amount of money. So I thought I will repair it by my self. So need help about the software name its use and how can I program it. If any of you guys know about it please provide me your precious knowledge. Use this printerest link for see my pm head(plc board) https://i.pinimg.com/564x/0e/d6/6c/0ed66cb9a1065ab10a07e0b9aadc6f0d.jpg Thank you (TIA) Masud karim -
Allen Bradley 1764-24BWA Series B
marianosanchez posted a topic in Allen Bradley / Rockwell Automation
Hi everybody. I am looking for the schematic diagram of the power supply for the Allen Bradley 1764-24BWA series B. I did extensive search on google but could not find anything useful (only user manual of replacement parts). Thanks in advance. Cheers. -
Good day! Please tell me the options for calibrating the touchscreen of the B & R Power Panel 100 4PP120.1043-31 Rev.K0 without BIOS. After the damage, the touch screen managed to calibrate. After replacing the touchscreen with a new serviceable one, it is impossible to "push" the buttons - you need to start above the button, off-screen. There is no project source. A faulty touchscreen also fails to do a calibration. Can I reset the default calibration settings? Where is the calibration table stored? Is there a way to immediately call calibration after power on? I would be very grateful for any ideas!

Anyone have experience with the old SLC-500s? I have one machine that is about 13 years old and I think they used a new old stock SLC-05/04 when they built it. Anyway I had a battery error, which makes sense since the battery was very old, and I lost my program when I tried to replace it, which makes sense because the capacitor which is supposed to hold the charge is very old. When I tried to re-download the program to the PLC, I could not connect, I realized my issue now was no null modem... and my driver not working on my RS-232 to USB converter. My question is: What is the port above the DB-9 port used for? It was labeled PROG, so when my DB-9 serial cable didn't work I tried a serial cable for a mitsubishi FX series on the top port... and.... my power supply died. Is this a common thing on SLC-500 power supplies? Can you short them by using the wrong cable? The weird thing is the fuse on the front was not blown. Is there a fuse inside I can get to and replace? We are planning on just keeping this machine a few more years so we don't want to upgrade it. The CPU was fine afterwards.

Hello All, I will first state that I am very new to the world of PLC's. I do the control drawings where I work. I'm trying to figure out the 1734 Point IO, specifically the 1734-IA4. The manual states "Module power is supplied from the internal power bus". Does this mean I do not need to run ANY power wires to the modules? The installation manual shows points 4,5,6 and 7 as "L1" wires?? The system I am designing, from left to right has the following: 1794-PS13, 1734-AENT, 1734-FPD, Followed by Qty. 11 1734-IA4's. I'm bringing 120VAC and 24VDC to the 1794-PS13. From the 120VAC terminals, I run wires to the FPD. From the 24VDC terminals, I run wires to the 1734-AENT. On the first 1734-IA4, I would think I should bring any power there, because its already back plane fed...….correct? Or DO I run power wires there? Thanks in advance

Modbus address register exchange between Melsec-Q series PLC and ME96SSHA-MB Power meter
RV3.0 posted a topic in Mitsubishi
Please assist me with the following; regarding the ME96SSHA-MB Power meter data transition with Melsec-Q series PLC; We acquire to read various values on dedicated Modbus storage address registers at the simultaneous into a Melsec-Q series PLC via Modbus (TCP or RTU) for calculation purposes. Naturally, since the reading of these variables are to provide accurate instantaneous results, it is a requirement that these values are to be read at one scan. However, as can be seen below, there is a gap in address register range – of which, if all of these are scanned simultaneously, yields an exception error when read. This error is only avoided by scanning these data sets separately – which is not ideal for our application – since accuracy in calculations is imperative. -

The plc runs for a minute and then the power turns off while the supply voltage is ok. I was sure that it is for the power circuit problem inside the plc. As I had a spare power circuit of cp1h and I checked it had same voltages output (5vdc, 24vdc & 0), I replaced it. Now I cannot connect it with my laptop to change to run operating mode. Could anyone help me?

Hello, I have a cp1h-y20dt-d (sinking output) plc supposedly to be wired to a servo controller. The pulse control method is Pulse/Direction. I've did some manual research on the PLC and found the following diagram attached Untitled. Since the diagram above doesnt show which terminals does it connect to in the CP1H side circled red, I want to ask if those connections belong to the following diagram attached Untitled1? If so, assuming im planning to use only Pulse Output1 (Pulse/Direction method) from the PLC side, is the connection from the first diagram no.1=CCW0- , no.2=CCW1- , no.3=COM (connected to -ve) *Note: these diagrams are from omron's manual SYSMAC CP Series CP1H-X40D_-_ CP1H-XA40D_-_ CP1H-Y20DT-D CP1H CPU Unit Your replies would greatly help. Thanks and best regards, Summer

How to get experience with three phase power
Park.CTRL posted a topic in General Topics - The Lounge
I got denied on a job interview, there might have been a few things but I think not knowing NEC and lack of experience with three phase hurt me. The NEC stuff is for another thread but how do you get experience with three phase? Unless you're in a shop already 3ph can be tricky to find. We talked about it at school in multiple classes but never anything hands on. Yet the descriptions for these entry level jobs all expect you to have a few years in of working with 3ph. It looks like I can make my own three phase from 120VAC with a small VFD. Maybe find some small 3ph motor at the scrap yard, get a new contactor and practice taking measurements/hooking stuff up. I've no problem building a trainer if I get to study up on 3ph and NEC at the same time. Crazy? Any advice? -
