Based on the spreadsheet in the post linked to by kratmel, you might try 9.7.60 if 9.8.31 doesn't work. Not sure if you can open a 9.8.09 project with VisiLogic 9.7.60 though. Of course the other option is to upgrade the PLC firmware. It isn't all that difficult.

Try 9.8.31. I don't know all the firmware versions and associated VisiLogic versions, but I suspect this one might work.

By the way, when you opened the project in your VisiLogic 9.8.91, it should have warned you that you were opening an older version project in a newer version of VisiLogic and also told you the version of VisiLogic the project was last saved with. Don't ignore that warning!

I'm not sure exactly what you're asking, but you can set any number of timers you wish using the same ML that you loaded from the master timer. You could easily load from master and set all 13 timers in the same ladder rung.

And just to add to and clarify: the firmware update isn't required because you changed the program - it's required because you tried to load the PLC using a newer version of VisiLogic. We recommend not doing that.

I do this frequently. Have a 'master" timer that you set on your HMI, then perform in ladder "Load Timer/Counter Preset" (under the "Store" menu) to an ML. Then perform "Store Timer/Counter Preset" to all the timers you want to set from the master timer. Easy peasy.

Are the iPhone and PLC on the same subnet?

Is this an internal network or over the internet?

Assuming you're using VisiLogic, take a look at the example projects that came with your VisiLogic installation.

In rung 2 you are continuously calling the MODBUS Configuration FB. You need to replace SB 142 with SB 2.

Which version of VisiLogic are you using?

Unless you've initialized another socket to Port 20256 for another purpose, or you've initialized Socket 1 for a different purpose, you're all ready for Remote Operator. Just connect to the PLC via Port 20256. Be sure you know the IP address and PLC Name and it should connect right up. I'm assuming this is all LAN and you're not trying to connect over the internet. By the way, no need for a SET coil for SB 168 - just assign the Power-up to SET.

All of the serial port parameters can be set on the V120 PLC within INFO Mode. It's a bit cumbersome, but it's all there.

When using Ethernet, you have 4 sockets available to you for simultaneous connections. Just use different Port numbers for each connection and they'll be fine. The default configuration for Socket 1 is set for VisiLogic comms (also Remote Operator) - Port 20256, and Socket 2 default is Port 502 for SCADA. If you are using Socket 2 for your SCADA then you are good to go.

The STORE function should work for that. You can store a value into either the Preset or Current for the timer.

Timers count DOWN and the Out Bit will turn on when the Current value reaches zero.

Geez, how did that get by me? Thanks Fernando!

I don't always start using the latest version of VisiLogic right away. Has this been added, or are you thinking of UniLogic?

When I program that function I get 1.65126 for MF 1 using 819 stored in MI 6. Do a search on MF 1 , MI 6, & MI 610 to confirm none of those values are being overwritten anywhere else in the program. Also, if those ladder rungs are in a subroutine, make sure that subroutine is being called in the Main Routine.

You have a large task ahead of you. I only have time to give you a few pointers and likely someone else with chime in with more. - There is a lot of information you can use on the Unitronics website. Download the spec sheets for your V130 PLC and the EX90 I/O module. Your V130 has built-in I/O which includes 20 digital inputs, 2 analog inputs, & 16 transistor outputs. Expansion I/Os can also be added. I don't have any experience with the EX90 expansion I/O module, but I thought this module could only be used with a different PLC (M90), but perhaps I'm wrong. The EX90 has 8 digital inputs and 8 relay outputs. - There are two ports that come standard on the V130 - the EXP port which is only used for adding expansion I/O modules, and a serial port which can be used for communication purposes, including downloading the program from VisiLogic. One additional port can be added. My recollection with this PLC model is that by default you cannot upload a program from the PLC to VisiLogic unless the original programmer specifically enabled that option (most do not). If you don't have a copy of the VisiLogic (.vlp) file, you may be out of luck on any program modifications. If you don't have that file you need to be directing as much time and effort as you can to locating it. - Unless you have a computer with a native serial port, be sure to purchase a USB-to-serial converter that uses the Prolific chip. The one I use is the Trendnet TU-S9, but there are others. - Your VisiLogic installation came with a number of example programs. Review them to see how VisiLogic works. The ladder logic is essentially identical between all the various PLC models. - Unitronics offers a number of video tutorials and webinars that can be found on this site and on YouTube. They're worth your time. Also, review the Help file that came with VisiLogic - it's very useful.

Perhaps I'm wrong, but I thought the OP was referring to the program in his PLC.

Apparently I was lost in a cloud and was imagining that the OP needed to change the timer within ladder and not directly from the HMI (as was clearly stated). I don't think I got enough sleep last night. Thanks @Gabriel Franco for helping the OP from being led astray.

Use function Store Timer/Counter Preset:

Pure genius! I love this feature.

This is where it's at on my computer: Be sure you have explorer set to show hidden files if you're looking for it in Windows File Explorer.
