Program for testing encoder
2rlp replied to kikitron's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Bear in mind the maximum frequency of the Samba 430 is only 30Khz, so with a 5000 PPR encoder, you are restricted to a maximum RPM of 360. You will miss pulses once you are beyond this RPM -

V 350 High speed counter
2rlp replied to Rog's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Will this work? with both High speed counter as well as frequency mode being used? For flow calculations, the need is for frequency -
Unitronics M91-2-T38 External Keypad
2rlp replied to infkawu's topic in Jazz, M91 PLCs and U90Ladder
You may be able to achieve the desired by using SB39. I dont have a M91, so cannot confirm -
How do I get out of this MESS?
2rlp replied to 2rlp's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Hi, Cara - jweav2223 and Saragani got the gist of the message & saved me the trouble of explaining my post. Saragani - Since I first developed my project and then imported it to the Webserver template, I have the logic that i had created. My major concern is that is there a way where I can have 2 different paaswords for the ladder modules? Ron -
Hi, I took the Advanced Webserver Template for V350, and built my project around it on a V570. After successfully testing the project, the system was delivered to the client. As a practice, before dispatching the system, I always utilise "Ladder Password: Apply to all subroutines in the Module". Now, when I am at site & wish to modify some section of my software, I just realised that I have to enter the password which was used by the authors of the Webserver Templates. I too do not want that my software be open to others * so need to lock my subroutines. Ron

Thanks AlexUT, Was wondering if its possible to send an XL sheet to the PLC thru webserver? Ron

Hi, I have used Unitronics to send emails. Is there a way that the PLC can receive emails? Ron

Lawry, U have asked a very important question. I need to know if Unistream's IO modules can be used on Vision PLCs. & if so, will it follow the specs as it would with Unistream or as per Vision PLCs. Thanks Ron

Thanks Joe, Very Informative. Cant wait to get one unit in my hands.

Need help with some ladder logic.
2rlp replied to NickB's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Dear NickB, According to your sketch, it does not seem that the Push Buttons are connected to the PLC in the right way, or may not be connected at all. Pl check if you can see the status of both the Inputs on line. Ron -
Vision 570 w/ 3 shaft encoders
2rlp replied to stgtech's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Why not use CAN encoders & eliminate the need of a M91 -
Redundancy
2rlp replied to 2rlp's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Thanks Joe. The client has now clarified that they would accept onle GE Fanuc or Allen Bradley -
Hi, Wishing all the members A Very Happy & Prosperous New Year 2013 Is it possible to configure 2 numbers V570 as a redundant PLC? The client needs a redundant PLC & redundant power supply. Thanks for your replies Ron

Reading Floats
2rlp replied to lawry's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Hi, Solved the problem by changing the 3rd party equipment's float format from IEEE to the Daniel format. Lawry -
Ressetting HSCs
2rlp replied to 2rlp's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Thanks Simon, I had also thought of using the same dual MI comparison method for detecting two of the fast occurring signals. However my problem now remains that I am also using an Encoder of 1024 PPR of Kubler make. I have to use these pulses to emulate a cam. The reset ( Z Pulse ) of the encoder works at slow speeds upto 20 RPM, but above this speed, tehre is no resetting occurring. I may now have to instal a snap in module just to acheive this. Ron -
Ressetting HSCs
2rlp replied to 2rlp's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Hi Damian, I am using an EX DI16AI3TO16 + 3 X IO DI16AI3TO16. As stated by you I/P 4 is the HSC or as I may call it the 5th I/P. I have configured it for "High Speed Counter" Only. Hope to receive a solution soon. Have to implement it at site tommorow. Thanks Ron -
Help With Resetting Timers
2rlp replied to russedwards's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Oops sorry! Did not note the equal to block. -
Hi, I am using 4 nos of DI16 AI3 TO16. I am using the 5th I/P on each of these as High Speed Counters without Reset. These I/Ps have bben used primarily to capture some very fast signals. I will be performing some process as soon as the value in the designated MIs counts 1. After the logic has been solved, I need to RESET the respective counter. I have tried my best, but am not able to do so. Immediately RESET HSC does not work. --{R}-- MI does not work. Is there a solution to this? Pl reply at the earliest Ron

Analog Input
2rlp replied to 2rlp's topic in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Thank you both Simon & Damian. The signal is analog. The overrange is set at 5.5V & at this I am getting approximately 19 mA. Ron -
Hi, I have an amplifier which outputs 0 to 5 V depending on the sensed condition. However due to an oversight, I had ordered EX DI16 AI3 TO16 module. This module has 3 Analog inputs of 0 to 20 mA. The amplifier specs state that its output impedance is 100 Ohm, the input impedance of the analog input is 190 Ohms. So on connecting the output of the amplifier to the analog input, I get a value of around 19 mA (978) counts in MI corresponding to the analog input. Is scaling the counts such tha 978 corresponds to 1023, the only solution? Or can the input be made to receive 20 mA? Thanks Ron
