Hi, I have one question about modbus communication by step 7 program such as attachment. Could you explain about that following this step? 1) What is the meaning of the operator? (the red characters) (id_o_a :="CONTROL_DAT", id_0_a) 2) What is the meaning or the purpose of the whole STL program? Thanks for your help in advance.

Hi, there. I have one question about Scan time pulse in Siemens PLC such as my attached file. Could you explain about the logic at there? Thanks for your help in advance.

Hi, I have a question about DP communication. That is the relation among the hardware configuration, FB, and DB declaration. Refer the attached pictures for understanding my question. The testing item is Yamaha robot machine using the DP communication. How can those communicate each other by any address mapping? Which information should I give the Yamaha engineer for the address mapping? Thank for your detailed explanation in advance. (Especially the address declaration of them)

I have one question about TCP/IP communication. Is it possible to connect each other such as the attached file between Industrial Ethernet and Modbus TCP at the same Hub equipment? Thanks for your help in advance. (Please, refer to the attached file)

Hi, there. I have a question about an electric wiring such as the attachment. There is some problem at the pointed connection between AC voltage and DC voltage in my mind. Can you explain about that? Thanks for your help in advance.

Hi, there. Can you explain about this attachment? At first read the #OB_SCAN_1 data, then compare 1 with that. After that the M0.5 set or reset to 1 or 0 following the RLO result. Is it right? Thanks for your help in advance.

Hi, there. I have one question about FLL instruction. Could you explain about that such as attached file? (For instance, 16#80 -> 16#FFFF FF80 /16#1234 5678 -> 16#78)

I have one question of Ground Symbols. Can you help me to understand those? Thanks for your help in advance. (Refer to the attached file.)

I have two examples of STL structure for Clock Pulse bit by two different programmers. The Clock pulse result is same each other.(0.1s/1s..etc...) But the STL structure and M addresses are different. What is the reason? Can you explain about that? Thanks for your help in advance.

I have questions about AWL file in Siemens PLC as attached pictures. Q1) What is the AWL file in the first picture? Q2) What is the meaning of the structure in the second picture? Thanks for your help in advance.

What is the meaning of this attached picture? I am not familiar with STL structure. Pls help me in details. Thanks for your help in advance.

I use the 1756-L73 CPU and the 1756-EN2T for the Ethernet communication with Mitsubishi PLC. The Mitsubishi ethernet card is the QJ71E71-100. Do you know the way to communicate each other except for the alternative ways, OPC or SCADA by Ethernet way. Only one to one way. Thanks for your help in advance.

I want to know the concept of the attached P&ID drawing. Please explain the concept of the P&ID drawing inside of the red box.(Boiler Control) Thanks for your help in advance.

As the attachment, I should control the pressure from 1st to 2nd step by step. The 1st Pressure Purpose Value and then stable time. And 2nd Pressure Purpose Value(the final purpose valve). In this case what kind of the control solution is good for this control? Just use the two PID functions one by one? Thanks for your help in advance.

I have one question about AOI function in the Logix5000 software. What is the difference between the cases that is the Checked-req or not at the parameter window? Please refer this help article as follows: ---------------------------------------------------------- Req Only use this field if the Parameter is required. This field determines whether the Parameter requires an argument. The Req field is checked and read-only by default for the InOut Parameters (because by-reference Parameters require an argument). Otherwise, the Req field is unchecked by default. Note that you can right-click on the Req heading to choose to check or uncheck all the rows in the Req column. A call to this Add-On Instruction does not verify if a required Parameter does not have an argument assigned to it. This field is not applicable for members of the InOut parameters. ---------------------------------------------------------- Thanks for your help in advance.

Nowadays I make a concept of Water Treatment plant. Unfortunately I do not have any experience in this part. So is there anyone who has the Water Treatment or other P&ID drawing? Thanks for your help in advance.

Hi, there. I have one question for the title, the electrician and control engineer. I have worked as that kind of job positions over 15 years after my university graduation. Until now I have lots of experiences at those parts. The Press machine, the automobile engine line, the chemical factory plant, the Bending machine, the water treatment plant, etc. Lots of travelling abroad. USA, Canada, Mexico, Brazil, China, Japan and korea. But nowadays I have one question in my mind. How long can I work this kind of job as the engineer in my country and in the world? Generally in Asia area the engineer age is too young. So the average age of the main engineer is almost 37 years old. The engineers usually change their positions to the sales part or having their own companies around the 40 year old. So I have lots of thinking in my brain nowadays. I just wonder about that kind of things around your nation in the world. How do you think about that? What kinds of things do you prepare for your future as senior engineer? Thanks for your reply in advance.

Thanks for your help, Guys. I have one question. When I use the Data Station Plus, DSPGT for this application, does not it need any PC or OPC for the bridge function? According to my search for the application, the DSPGT need a PC or OPC finally for the change of the protocol. You mean that The PLCs can communicate each other directly by the DSPGT without any PC or OPC? Your answer in advance.

I use the siemens PID function for my project. But I am a new man in the usage of PID function(FB41). What can I do for the suitable usage of PID function? Usually most of engineer make a setting value on the GAIN / TI / TD for PID control. Should I set the value of the PID function at the DEADB_W / LMN_HLM / LMN_LLM? Thanks for your help in advance. (*Refer to the attached file.)

The local measurement unit should communicate with Main PLC by the serial comm port(RS-232). How can I make the PLC configuration using the PROSOFT communication module? (MVI56-DFCM or MVI56E-GSC are right for the communication?) *Please refer to the attached picture.

Hi. I want to know the meaning of the abbreviation in this P&ID drawing at the attached picture. For instance, YSTR / SHX /XV / PG / SIC / BRV / PR Thanks for your help in advance.
