    Ok I was finally able to send email to my local exchange server account using my local exchange server. Without getting into details, my problem was in the settings that I used in specifying the Account. A logfile would have saved me a lot of effort. The following link was instrumental in digging out the answers: Microsoft : Use Telnet to test SMTP communication on Exchange Servers Yea!

    Thank you Joe! :) is used for isolate board and fit board to Jazz PRG dimention. You won't believe it, but a broken arduino + chip for correct galvanic isolation works as a programmer or PC232 port. The main task was to create a CNC machine based on Jazz and the free Arduino GRBL CNC conrtoller based on a stepper motor. It installed to Jazz like JazzPRG. It had to perform only two standard movements but with a complex 2D trajectory. Everything works ... Jazz 10 replace original old puter and ISA CNC card in it!

    No. One way they made the Jazz lower cost was to eliminate the TTL-RS232 converter chip and circuitry. The target for this product is OEMs, and if you know anything about dealing with that market they value low cost almost above all else. A JZ10-16 is not that terribly old. I have a couple in stock. You don't mention what part of the world you're in, but a JZ-PRG programming port is $47.00 US. Joe T. P.S. - @kratmel - you are hardcore indeed. That looks like a hackulation I would try to build to save a nickel. The mega heatshrink is a nice touch. 😁

    I tried to research this port and the original programming adapter for my own needs. Making your own is probably possible (and I even managed to do it with the USB interface- on foto), but there are two major problems - there is a 3.3 volt communication port in the PLC that requires a mandatory galvanic isolation that is in the original adapter. Therefore, I recommend listening to the above. You should use the standard devices listed in the topic for programming this PLC.

    Of course there is a practical limit, but I haven't run into it. When you consider that Ethernet runs at 100 Mbit/s, simple math says that in 500ms you could exchange 50 Mbits. Of course there is overhead, so I'll divide that by 2, giving 25 Mbits. Divide that by the 32 bits for your INT32 registers, then you get 781,250 INT32s can be exchanged. I'm sure there are other factors of importance here and there is a MODBUS limit of 256 bytes per request, which will be your primary limiting parameter.

    Used to have this issue on v1040s with a lot of screen elements. Clicking off of an item onto a blank space would take a while. Trick was to ctrl+click to deselect the item. Leaves you in the same state of having nothing selected, but without the wait. Nick

    Hi Neels, UniStream is only an SQL client. I'm not aware of situations where an SQL client can respond to requests. I have done some quick google searches and there are situaitons where two SQL systems are set up as master and slave where they can request data from each other, but in those cases both master and slave are both SQL servers, and the purpose is to keep backup copies of data. Just another thought, if the customer installed MQTT broker and client software on their SQL server, they should (?) be able to set up the MQTT client as a subscriber to the MQTT data, and it would push new data to the SQL databse. The PLC would only publish data as it was relevant, which would optimise the data flow to the main SQL database. There should be controllability on the update rate at both the subscriber end as well as the publisher end. Going back to the idea of the UniStream connecting directly to the main SQL databse, It is possible to set the PLC to only push data to the SQL server on change of state. Maybe the server could send an SNMP packet to the UniStream that would trigger an SQL push? As I said, just some thoughts, based on general principles and completely un-tested... Simon
