Theoretically - yes. Jazz doen't care if the module is JZ-PRG or JZ-RS4.
But:
1. JZ-PRG needs external power. That's why it uses 6 wire cable. When you connect to PC, the computer provides this external power. But when you connect to third party device, you need to take care.
2. JZ-PRG is passive port. This means that there needs to be active port on te other side ot wake it up. Even if you supply power properly, you will not communicate between Jazz and Jazz. Additional problem is, that practically no producer states ifthe port is active or passive.
Bottom line - highly recommended to use JZ-RS4 module and not JZ-PRG for any communication out of simple connection to PC or modem.

In Israel now is Weekend, 9:40 PM.
Bon Nuit!

I really don't like your way. I'm not surprised you have problems!
The way I'll recommend:
On a positive transition of the bit, which needs to give command to send, SET a MB "Request to send"
With N.O. contact of "Request to send" and N.C. contact of "Funciton in progress" (See FB Protocol - Cofig module!) activate Send block. At the end of this net RESET "Request to send" MB. This way, even if the port is busy in the moment, the controller will wait a little and will send the command. There will not be mess or commands missed.
Then, in Scan module, when the bit "Session complete" becomes active (N.O. contact, there is no need for positive transition)and the number of received message is the one you expect, you will SET another MB " MY Message arrived" and will activate "Reset buffer" Reset buffer block resets immediatelly MB "Message arrived" (the one from Scan module).
You can use now the bit "My message arrived" as condition to send reply - the way described above.

Practically not.

Theoretically, there is no problem to use it as stand alone PLC. But please note - there is no battery inside, so on power off it will loose all operand values. If this is not a problem...

It depends on the other device needs. In V570 you can send out string in the same scan you received confirmation that the expected string is received and recognized.
If the other device don't like such fast reaction, you can put a small timer from the bit Message arived to the Send block.
I gues you're using FB Protocol.

Hi Mikael,
RS232 is not protocol - it's a physical layer.
Can you post the telegrams you need ot send and receive?
Which controller you're using?
-
4G per file - Microsoft limitation. Please note - you can hold up to 320 (!) files in one SD card!
-
You can set all numbers in phone book as indirect.
-
Did you set SB168?
Loosing connection is something relativelly "usual" in Ethernet networs. Practically any unit has some recover system. Please also consider setting values in SI106/110. This needs to activate the auto recover system in the controller, if needed.

Hi Jim,
There is no way to export displays from U90Ladder to Excel.
Please note - Enhanced Vision models (V130/350/560/570/1040) support powerful function String Library. It let's you in an easy and intuitive way to support up to 16 languages in your application. You can make your program in one language, taking all texts from String library, then export relevant library to Excel, translate to other languages and copy from Excel the translated strings to other libraries in the controller. This way, the translation in fact is no longer part of the programming itself.

I think PID will do the job. 15 seconds is a lot of time! As I understand the system, you need to set narrow Proportional band, let's start with 50 (5% of whole range) and relativelly big Integral time. This way your press will apply full power very fast to pressure, relatively close to desired and then "slowly" will increase the pressure to desired.
Important note - there is a very helpful tool - PID server. You can find it in VisiLogic > Tools menu. This software will let you to "see" the process and will help you to improve it. In case you will need our further help with tunning the system, you can attach your application and log files from PID Server.
In my opinion in your specific case Autotune will be useless.

Triacs also have their disadvantages. In this stage, we prefere to use more universal relays (dry contacts and, at least theoretically - higher curernt). One can easilly use unit with transistor outputs and external SSR.

you can attach the file to your post, or you can send meil to support@unitronics.com...

Hi Kostya,
This is a known iassue. HSC on expansion moduloes cannot be reset in the way you are trying.
In U90Ladder > Help menu > Simple application > Motion control there is demo application HSC Reset.
It's here attached...

Usually the display is tghe Master. I expect Jazz ot be the Slave.
-
Dear Kostya,
SB3 is 1/2 sec ON and 1/2 sec off. I don't understand what exactly you want to perfom, but if you want to reset the counter, you need ot use special procedure. Please take a look on examples (VisiLogic > Help menu > Examples...).
-
Sorry, but:
- the object will remain with the colors as now.
- There will not be USB in V570/560.
At least such changes are not planed for now.
-
What you selected in Hardware configuration? If you select HSC plus reset you need ot connect Reset signal ot I6.
-
If the display supports Modbus RTU - yes, you can relativelly easy connect Jazz ot it. But maybe in case you need bigger display you can use, for example V350 or even V560, V570... I guess for about the same price as Jazz + external HMI you will enter in a totaly different world of control and HMI.

Hi Kostya,
As you can see in the attached capture, you can define one high speed counter in IO-DI8-RO4. In attached spec you can see (bottom of page 6) that this is I7 of the local module (see hardware configuration for the real address in the system)and the max frequency is up to 5 kHz.
Note: HSC is supported only by I7 of the module! There is only one HSI in this module.
In hardware configuration of the project you need ot link register (MI) where you will receive the counts. The update will be at the beginning of each controller'scan.
I hope this answers your question.

Dear Tester 2,
You need ot know:
- If your slave (Moxa supports TCP or UDP). I guess it's TCP, but anyway, check it.
- What is the IP number of your I/O module;
- What is the port number;
- What are the addresses of the relays there (Slave address table).
Having this information, you need ot set Vision FB Modbus IP to set coils with defined addresses. You can find working example about Modbus IP Master on VisiLogic > Help menu > Examples > ... > Project examples > Communication > Ethernet > Ethernet Modbus IP.

Unless it is impossible in M91 to assign on the additional unit an output for the counter?
Can yo explain what do you mean? Maybe you can explain in Russian?

Or to your IT manager?...
Problem with PTO
in Vision & Samba PLC + HMI Controllers & VisiLogic Software
Posted
Hi,
Such reaction is "normal".
If you give PTO target, it will stop immediatelly when it reaches the target.
If you Reset RUN bit, it's operated at te end of the scan, so some delay is expected.
What yo can do to improve te reaction:
1. To read immediate the input (Read Physical inputs - VisiLogic > More menu > Immediate) within 1.25 ms (Enhanced models) or 2.5 ms (all Vision PLC).
Or:
1a. Connect the sensor to HSC (reload) and give it Target = 0. When the signal comes, the congtroller will enter immediatelly in a dedicated subroutine.
In Interrupt subroutine, SET one "Stop" MB/XB.
In the normal scan, each few nets add a net "When "Stop" bit active - reset it and jump to End.
With this procedure the reaction time of thhe congtroller will drop from up to 2 scans to few ms or even few tens of microseconds (option 1a with enhanced models).
Please let me know if you need more help...
