Your Application does not totally depend on PID loop whether need to do more program for your variable setpoint. PID loop just control the process according to your setvalue. have a look on attached reference _Continuous_Control_with_SFB_41_FB_41__CONT_C__.pdf

Dear all, i am working on the distillation unit with S7-314IFM without Memory Slot and OP17-DP. i am trying to upload the project of PLC but it is password protected. could anyone have any idea to crack the password and able to upload the project. i have try to several forums but invade. i need to complete solution to crack the PLC password. waiting for reply

HMI and VFD does not support DH485, but both can support modbus protocol. and i have decided to communicate through modbus protocol. Should i use the interface adapter (AIC) for using the Modbus with ML1200 or this can possible with PLC com port?

Hi every body in this forum, I am workin on a project that of using the DH485 communication in this project. project scenerio is simple but i am facing the problem that how to program that type of system. Description: there is a Machine with HMI and a VFD connected with ML1200 via DH485, How could we use the communication instruction to drive the VFD from HMI? if anybody create a ladder for this instruction i shall be thankfull to him, Model and Make: HMI-> MT6100i (Weintek) VFD-> FR-D740-2.2K (Mitsubishi) PLC-> [Micrologix 1200] 1762-L24BWA (Allen Bradley) Regard, Mohammad Daniyal

Currently the HMI and PLC are connected on RS232 communication port, but VFD is Operated Manually from its own Operating Unit. Yes- HMI is read from and write to PLC No- The VFD does not operated from PLC. VFD is totally stand alone operated. but now we want to operate it with PLC commands. DO you have any solution.

no-body knows about this issue. can anyone help me.

The attached image may clear the problem that i am facing, kindly help me with this issue.

Thank you for your kind help, i have been concern with the manual.

there is a query about the Siemenc Product. Is S7-300 is compatible with TD 200. if yes how can we set the Alarm msges Data base in the S7-300. if anyone have more detail about my above qeury please guide me, i am working on this type of Scenerion.

All Rockwell Softwares supports with windows XP Pro, and later. Install the windows XP Pro edition.

any body would help of my issue.

I have a project that was designed in RSView32 v7.5, and i am open this project in v7.40 some of the graphics screens does not open due to older version of Active X Control, and display a msg for install the newer version of Active X control. i have been try to install new version of Active X but the msg still displyed every time when i open the graphic screen. kindly suggest me which version should i install on my pc however i could open the graphic screens. or any other settings will be required for this issue.

i am trying to Open the screen "Activity Log" and "Alarm Log" ActiveX, those graphics screen should opened but the ActiveX Control area does not show any thing and still blank. however before open the ghraphic screen the error msg should display " Unable to load ActiveX Control for display <graphics screen>. cause: RSView Log Viewer : Newer Version of ActivX Control required". do u have any idea which activeX control should i install.

Hi All Members, I am facing the trouble to RSView32 program. When i open the project in rsview32 its stop on 40% of opening project and take too much time to open the tagServer (WatCom SQL Database Engine), could anyone give any suggestion for solve this problem. Regards Muhammad Daniyal

Dear All, we have the 2-wire inductive switches N.C (NBN4-V3-N0-Y51517/P+F) installed in the Positioner mounted on the valves for feedback, the switches normal operating Voltage are 8VDC to 16VDC that could not be fisible to directly operate the PLC Digital Input. Please solve this issue that we could operate the PLC Digital Input with thoes switches. we are using Mitsubishi FX1N-40MR, and the SS point connected with the -VE/24VDC we have tried to wireup them with an optocoupler (TLP521-1) in simatic but still invade. if anyone have the idea, please share it with me. thanks and best Regards 051517_eng.pdf

please see the attached image, whom i have been working on it but not functioning. Please mention if there would be changes to made.

I have 12-bit Analog Output (6ES7-332-5HD01-0AB0) module that illustrate the SF indication ON. while the CPU is running in normal condition. However i have replaced the module to another slot but the module still indicating the SF LED. Could anyone tell me how this Fault should be removed. Regards

Good Day, Dear friends, My Problem related with the turbine Flowmeter who has the pulses output with respect to flow of fluid. E.g 10PULSES represents the 1 litter/min. the flowmeter does not have any converter that convertes the Pulses to standard Analog signal. So i want to convert the Flowmeter pulses in Analog format or any scalabel form by designing in the Ladder Logic. if anybody have the idea of femiliar with this scenerio kindly guide my or help me through your experience, therefore i could complete this task. it is requested for the quick responce by you people. Thanks & Regard. Daniyal

Thank you very much Inntele, Good Luck

Dear, In my earliest posts i just need an idea that how to make this application applicable in PLC logic, so thats why i wrote the spose figure for making reference. while now the information i gave you are as per my actual figurs and these figures are according to my flowmeter specifications (100Pulses/Litter), because we are now just insert the designed piece of logic in my program as you have mentioned. the minimum flowrate should be 4gallon/h.

1) X0 2) 0 to 100gallon/h (1Litter/min = 200Pulses) 3) 20mSec including the communication. 4) unused Devices from D5000, M2000, C10 5) Modbus 485, 9600bps, 1-Parity, Even, 1-Stop please dont hasitate for further information

Ok i need your help to complete this project. kindly tell me which parameters you required for this.

Its great regards, i want to just make sure the unit that you have been mentioned with comments (D2 = Liquid Flowrate (L/min) in the program. otherwise its an idea that can be modified according to my requirement. Thank you for your great Help and the giving the idea.

Thanks you very much, but there is a problem with your design logic, the program updates the flowrate figure after 1 min when timer reaches the setvalue. While our need is that flowrate must be continuously update its figure by the short interval of the may be less than 1-sec. with this condition we are unable to get the actual flowrate figure during 1min when the timer is running. try to resolve the logic that calculate the flowrate when the flow of liquid increase or decreas. thanks and regards
