Dear Joe Thank you for your reply. Looking into it that is what I finally figured out. Therefore it is not worth the cost to engage 16 outputs just to read the content of a single MI. I will try and accomplish my task in a different way. Thank you for your attention. Petros

Can anyone suggest how to connect an lcd (7-segment) large size (8 to 10 cm height) 4-digit numeric display on a V120 OPLC, just to broadcast the content of an MI? That is, when the FB (Num to BCD) is used, how does the 7 digit LCD communicate with the PLC? Thanks Petros

Hello Everybody. After a few yeas absence from the forum, here I am with a 'stupid' question! It is the first time I will use the Alarms feature of Visilogic (Enhanced) since I used to build my own (or rather modified sample application!!). As I understand from help, when alarms happen and are called in a display, this display will be as shown in help. What will happen with V130 OPLC which has no touch display? Will the panel buttons be automatically assigned the alarm button features (alarm acknowledge, etc) Thanking you in anticipation Petros

Hello, Can anyone suggest a way to convert a value into a pulse output? I need to convert a numerical value range into a predefined frequency range pulse. Thanks Petros

Dear Simon, Thank you for your explicit reply. It seems that what you suggest may resolve the issue. However, I would appreciate a comment from a Unitronics technical person, and possibly an update on the help file...... Petros

Can anyone suggest why setting SB193 (deleting sms messages from sim card) does not do the job? Recently I had to visit a remote installation just to insert the sim card in a mobile phone to delete the messages. The system had just stopped accepting sms messages because the card was full. In the ladder, there is a weekly setting of SB193.

Hello eveybody, Please advice whether there is a way in Visilogic to select which data table to be the current one in use, by loading 'its' id number in a register, for instance. Thanks

Dear All, Thank you for answering / commenting on my suggestion. I agree with my friend Emil about the cost of such a dedicated / specialized module, but this module as described by Emil would be suitable for power analysis, including harmonic content, THD, min. max. voltage and current values, etc. Perhaps it is my mistake to have written power analyser in my original post - a module with the described inputs but with 'normal' analogue inputs would be suitable for power metering, alarming, instant (average) values, etc - I believe, without being an expert, that this would not be so expensive. Imagine all the benefits an OPLC (especially the enhanced family) could support for such a meter!! Anyhow, it was just a suggestion - no hard feelings if not implemented!! Best regards to all. Petros

Hi to everyone, For an OPLC to be accessible from the Internet, the local network it is connected to must have a static IP address. I believe there is a way to access an OPLC even within a network with dynamic IP, provided some further action steps are taken. Can anyone help us on this with detailed explanations how? Thanking and awaiting for news!! Petros

Dear Keith, Thank you for your answer. These are exactly the issues I was worried about. Thus I also posted a request to Unitronics people to have a dedicated module considered that will enable such applications. Petros

Have developers/integrators at Unitronics ever thought of intoducing Power monitoring modules? Then Unitronics OPLC's will make perfect and cost effective Power meters / analysers / data loggers - a very 'hot' product at this time with ever rising energy costs. All needed for such a module is: 1.Three 0-5A analog inputs to accommodate the current CT's 2.Three 0-600V ac/dc inputs 3.One Neutral input, and 4.A temperature probe (eg PT100) input. 5. A software FB to calculate/measure the frequency from a voltage input Looking forward to Unitronics' response. Petros

Has anybody ever tried to use the PLC to make a power analyser / meter? It must be fun! Do you have a source for good CT's and PT's?

There might be a problem with SB150. Try setting it ON and OFF by a command (it could be an MB within the drum sequencer) and not directly in the net. Keep us posted and good luck.

Does anyone know a reliable source for analog input electronic dimmers?
