Is this true? and how does one avoid this

I think your default gateway in your Card Init is wrong

Remove MB90 from rung #1

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

I have Micrologix 1400 plc connected to Omron NS10-TV00b-V2 HMI. Micrologix 1400 has two serial ports (RS232/Rs485 isolated and 232c non isolated port). I want to connect second Same HMI(exect Mirror) to the PLC. what hardware will I need?
Omron HMI has two DB9 serial portA and Port B. And PLC has 8 pin Mini (RS232/Rs485) and DB9 (232) port. Also both has ethernet ports too.
Currently 8pin Mini from PLC connected to one omron HMI Port A.
Where is the relation with Unitronics

Will this work? with both High speed counter as well as frequency mode being used? For flow calculations, the need is for frequency

You may be able to achieve the desired by using SB39. I dont have a M91, so cannot confirm

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?

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.

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

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

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

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

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.

Why not use CAN encoders & eliminate the need of a M91

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

Hi,
Solved the problem by changing the 3rd party equipment's float format from IEEE to the Daniel format.

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.

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

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
How could this happen?
