Technical support / MODBUS ASCII vs RTU
« on: February 27, 2002, 11:24:27 PM »
What are the differences between using ASCII/RTU?
What protocol is more efficiently?
Thx

Technical support / Timers
« on: February 27, 2002, 11:47:27 PM »
I used one control panel and one T100MD-888+.
From the control panel I change values for timers using this code :
FOR I = 11 TO 19
SetTimerSV I-10, DM
NEXT
In the 1st Scan I use
FOR I=1 TO 9
DM[10+I] = GetTimerSV (I)
NEXT
When I cut the current and plug again the new values are lost.
Could you please tell me what I need to do for retaining values!

Technical support / Slow communicatin

We used an EXOR control panel and a TD888+
The EXOR is setted to work at 9600, 8, N, 1
Same the PLC. The protocol is Modbus RTU and the time-out is setted at 5 s and number of retry is 2
There are some delay between pushing the knob and the start the hydraulics.
Have you any idea about how can we improve the speed?
Thx
