In fact , yours tutorials should be paid by Siemens , you're explaining times better than the lectors in their own videos. I learned programming because of you. Thank you very much for all your work!!!

[@Gerd_H]

Thank you! You have a very good ability to explain first of all the main things in a simple way.

[@mikeman3128]

This was excellent! A lot of information and good explanations for everything! Thank you!

[@mortenlund1418]

You do not know how helpful this was. I have a one day practice at school tomorrow with TSEND and TRCV. We have to send bool, real, word and string. Thanks you so much. Nice chair by the way.

[@fohadgh3136]

thank you so much indeed dear Mr. Phillip. This video is one of the best videos I've ever seen in my entire life because of having completely understood how I can make an easy connect between two PlCs in S7. I have no words to express my deep gratitude to You for having made this kind of vidoes.

hello and thanks for all the great videos. I have a problem and hopefully you can help. I am using a PID compact controller to control a hydraulic proportional valve, the ouput of the controller is 0-100%. My valve is working with 5V neutral position ;5V- 2.5V pos A ; 5V-7.5V pos B. anything below 2.5 or above 7.5 is a error and the valve will trip. How do i go about changing the output of the PID to work with my valve. its a Danfoss valve

Thanks for your videos. I have learnt lot. I just have used the same concept to connect two s7-1200 plc's ( by TSEND-C, TRCV_C) but not working. Is there any restriction between s7-1200 and s7-1500 ?

[@FiFa_]

Hey, thank you for the awesome Tutorial. Plc 1 to PLC 2 works fine. But i have problems with Sending from plc2 to plc1.

[@saje92able]

Have you find the way about this sir? I'm having the same problem

[@Izual001]

Hello, I have a question. Can you use a TSEND_C and a TRCV_C on the same port, or is it better to open a second one for two-way communications between PLC's?

[@maysaraharoun7110]

Hello there, thanks a lot for the very useful video, I have a question please, can I implement ISO-on-TCP communication using S7-1500 also? if yes, how to include the library that contains these functions? Thanks in Advance

[@javierpesinaoyervides8049]

Hi , very good video, is possible to use this TSEND_C and TRCV_C instructions to connect S7-1500 to a Compact logix Allen bradley PLC by TCP?

[@emilemouratis5403]

Hi, thanks for the video. There is a problem when many PLCs use TSEND_C to the same PLC. The receiving PLC seems to be able to connect to just one of the senders

[@sarahlabidi6558]

Nice videos, thanks please is this two block used during modbus protocol commuication ? exemple: if we want to change information from plc siemens to yokogawa dcs, we use this two block TSEND_C + TRCV_C ?

[@uzairhussain4232]

HAHHAHAAH loved the ending lol. Im working on PLC and had very basic knowledge hoe to create ladders only. Your videos are very helpfull. this is 4 years old video , is there any new way and easy way of cummunication between PLC and external device?. My role is to program the PLC S7-1500 to receive and display data( band width, power supply level/voltage etc) from a micro controller. It will send a string of data how can i break that down for my PLC, as i am New and to this and have very little knowldge ( will look to see if there is any video on this in your list)

Sir, How to add input in plc 1 suppose if i want to chose send data from 1st input of hardwire plc or 2nd input of hardwire plc and so on.so it should be reflect on other plc 2

Hi! When we send data to another PLC using the same functions, the port number has to be different, right?

hello, thanks for excellent explanation, can i ask if you could explain how to communicate with an external Ethernet IP device (has own IP address) with CP1243 communication module? many thanks in advance

[@lorenzobalducci8882]

I have a question and I hope someone can reply here :) I have a TSEND_C block that is sending a multicast packet every 100ms and everything works fine since I connect the PLC to TIA portal. In that moment seems that no packet is sent for about 300 milliseconds. Why this behaviour?

[@Ashishchabha]

Can we use TSEND function block to send data from Siemens S7-1200 to Omron NJ?

[@andresparedes3636]

Hi thanks for your videos what i have to do if from de same plc i want to send and recieve data?

[@tekamtash4868]

Hi Sir. Have you created the DB 2 before calling Tsend-C?

[@mikeleaman1768]

Have you set up a T_COMM connection between an S7 1517 cpu and a Control Logix L84 cpu using the 'on-board' ethernet port on the Logix cpu? We are having problems setting up this connection with this hardware setup.

[@GorgoN555]

What about connectin ID? Can it have the same value for sending (TSEND) and receiving (TRCV)?

[@rodrigueroland]

===> Would it be possible to do an "HTTP GET Request' with an S7-1200, please? Siemens has released a library (LHTTP) which is coded in SCL (state machine, 2 blocks TSEND_C and TRCV_C). I've removed the "DNS" part (and TLS too...) But it's not working and I'm not able to debug it because S7-1200 doesn't support breakpoints in SCL. Thank you :)

[@VladKolovrat_95]

Hi @Hegamurl, I have a issue with the communication in this way with two S7-1200. I'm trying to send from one (PLC_1) side to the other (PLC_2) and this goes well. But, when I try to do the same thing but from PLC_2 to PLC_1 the TRCV_C block displays an error and the STATUS display the HEX Code 16#8A7F. This code does not appear in the manual, so I don't know what it means. Can you help me with that? Have you ever seen that status code?

[@2004michacz]

It is a really awesome video, thanks for that. Can we use TSEND_C and TRCV_C for the communication between PLCs in different TIA projects? I have a problem with that...

[@hegamurl7434]

Hi Borys and thanks! Of course you can use those blocks throughout different projects (even with other tools than TIA Portal)

[@2004michacz]

@@hegamurl7434 Thank you very much again. I've already sorted it out. I realised, that I didn't download hardware to PLC after changes in the project and that's why it hadn't worked. I'm really impressed by your videos. They are brief with maximum information and a hint of humor, which makes them very helpful and entertaining at the same time. Greetings from Australia!

In S7-200 I found some special byte for free port mode communication such as SMB86, SMB94,....where can I find it in S7-1200? Plz help, thank you.

if I have PLC1 as using TSEND_C and PLC2 TRCV_C using Connection ID of 1, How does PLC1 receive data from PLC2? Does a new connection need to be established or can I use the same connection? If I require 6 S7-1200s to communicate bidirectionally would this limit me to 3 1200s

Both PLCs have connection ID = 1 does it need to be same ?

hey, first of all i want to say that you make a really good job with your videos. I learn almost a lot of them. Unfortunately i have a problem, i want to send and receive vice versa from a cpu315-2 Dp to a 1212DC/DC/Rly. The problem is i can use only simatic manager for the cpu 315-2 DP (with a cp to connect via Ethernet) and the other CPU (1212) does only work with Tia. Can you explain me how i can connect them. Thank you for all of your videos and hopefully you can help me.

[@joerg385]

No way to migrate the step 7 classic project to TIA? Otherwise you can easily use put/get functions (if there's not to much data to be passed, limits of put/get are shown in the help system). You can choose if you want your 1200 to 'put' and 'get' data to the 300 or just 'put' or 'get' on either device. For put/get you can setup and use unspecified S7-connections. Just remember that you have to enable put/get-communication specifically on 1200/1500s. No need to do this on your 300. ps: also remember that the transfered data is not consistent!
