value update interval very long

Admin
Hi all,
i build trial scada project for monitoring the Engine parameter.
the engine control Module is DEUTZ TEM
where the comm. protocol is 3964R/RK512 with TTY interface.
Baud rate = 9600
i use TTY to RS232 converter and than from RS232 i convert to Ethernet

[TEM]--->[TTY to RS232]--->[RS232 to Ethernet]--->[Indusoft]

DATA BLOCKs : 8
on 1 DATA BLOCK have 64 WORDs or 64 Tag
• priority TEM: low (slave)
• character time-out value: 220 ms
• answer time-out value: 2 s
• number of attempts to get into connection: 6
• number of attempts to transmit: 6

my problem is , the value update interval each TAG until 9 sec.
so how to do reduce the update interval to 1sec. ?

Thank you.

Regards
Heri
  • Hello Heri, I Know that you asked some info for this issue long time ago, but I'd like to post an answer not only for you but for other people too, because I was having the same problem few months ago.

    I am working with a different driver, MOTCP. In my project i configured up to 93 standard driversheet and my whole conmunication was really slow.

    What I did was to reduce those Sheets to 67 and as a result I enhanced my comunication speed significantly.

    Maybe is you do something like this in your proyect, you will get the results you want. This issue is caused not only for the amount of sheets that are configured (each sheet can be considered as a Request, each request "demand" some time to be process for your device), but also for the priority that IWS assigned to its several tasks, like the schedulers, maths, recipes, global scripts.

    Well, I whish that this comment help you somehow.
