Thanks Joe,
I should be receiving another V700 unit tomorrow - it should enable me to get any comms sorted and tested in a more 'isolated' manner. No doubt I'll have a few more questionsin the coming weeks!
-
Turned off firewall.
Still nothing.
I'll give up as well then.

Thanks Aus
MB56 needs to be either a positive or negative transition contact. It's sole purpose is to trigger the call, not keep on asking for it all the time, or never ask for it, depending on state. I think Alex probably meant this, but said toggle which you have taken literally and put in a toggle -(X)-.
No, MB56 is just an on/off switch on the HMI panel
Some of your questions relate to basic networking knowledge and I suggest you learn a little more about this from the myriad web sources available.
I am doing, 'til 4 o'clock every morning
It is also possible that your PC's O/S may be blocking the inward request via it's inbuilt firewall. What are you using?

i tried 169.254.180.1 but still nothing
-
Hmmm yes, this looks to be for the wireless adaptor. ipconfig doesn't show anything for the ethernet adaptor. How do I find this number?
-
What is an IP address you send ping to?
Parameter B of the PING FB is 169.254.180.182 (as identified by ipconfig)
Is this IP inside or outside of your network?
This is just a direct connection between laptop and PLC only
How you configured PLC OP, Mask, Gateway?
Details of TCP/IP INIT are: IP Address D# 169.254.180.200
Subnet Mask D# 255.255.0.0
Default Gateway D# 192.168.1.1
Does your network require MAC address registration on DHCP Server and Domain Controller?
I don't know anything about this.
Thanks
Rob

Thanks Alex, I changed MB56 to Toggle on the HMI but there is still no output from the PING FB.

Hi
I hope somebody could help with some basic questions and problems with a V700:1) When assigning sockets and ports do I have to make any special considerations
for the connection of Visilogic?2) Taking one step at a time I'm successful with direct ethernet PC-PLC uploading and monitoring
(although this is with straight cable NOT crossover - don't know why!) and I'm able to ping
the PLC (169.254.180.200) from PC(169.254.180.182) but when I try to ping PLC to PC nothing happens.See attachments
Socket 4 is ICMP
3) Also will any extra FB's need to be added to the example posted June 21 2017:https://forum.unitronics.com/topic/4746-condition-to-close-a-socket-on-v700/
to allow successful downloading of data-tables?
Thanks,
Rob

With Joe's code and an LED & Resistor across the 'Step' pins I could see that the voltage level
was pulsing correctly.There was also a steady 24V across the Enable terminals.
I tried to control the 'Direction' output (O2) with the original code example but couldn't get this to
work although it did work when conventionally addressed via ladder logic. I don't know why this is.So it must be the motor that's faulty or incorrectly configured - I'll swap it with a 2nd one to see.
Thanks everyone.
Forgot to mention: Teknic's wire colour codes should be ignored.
-
Thanks Joe. Now I know where to look.

Initializing & Resetting the PLC gives the same results. I reduced the Velocity
down to 125 which gave a longer time before 'at position' was reached but O0-O3 remained
at a steady zero on the laptop display.Could someone please confirm whether or not I should be able to see the outputs
changing during F9 Online mode? - just in case these PTO modules somehow control the
outputs in a different manner to the ladder code I'm used to. -
.... not too familiar with Unitronics stuff but the code in question is in the Main Routine of the Main Module so I assume it is being called continuously.
I'm also pretty sure I did a few Initialise and Resets because early on, after a main power off - power on cycle, I had displayed Config Success = FALSE and
Profile Success = FALSE. I think these changed after an Initialize & Reset. But I will double check again tomorrow.
-
Well, the wiring checked out ok. A clocking circuit 'conventionally' assigned
to O0, O2 and (for the hell of it) O6 resulted in their corresponding terminals
pulsing between 0V & 24V as expected and as indicated in F9 Online mode.These outputs could not be seen to be switching like this when the PTO ladder modules
were used so is there some output assignments I'm missing or jumpers or hardware
configuration still to consider? -
Thanks for that Aus,
Yes the motor is connected and it is lightly loaded.
I realize that with scan time issues online viewing of the Step pulses would be problematic but was thinking that the Direction output would be of a much lower frequency and seen easily.
...think I might have to see if I can remember how to use my scopemeter !
-
Thank you Isakovic,
Yes MI12 changes as expected along with the HMI display in general although I still cannot see any of the outputs changing state when in F9 'online' mode. The motor direction settings seem to also work ok on the display and within the PTO function blocks but again I don't see the corresponding output (O2 I think) change.

Hi Folks,
I'm trying to control a Teknic's SDSK stepper-type motor with a Vision V430 using its PTO functionality but with no success. I don't know if it's a software or hardware problem. Should it be possible for me to see any of the high speed outputs changing state when viewed in Online Test (F9) mode? Because at the moment everything seems to be dead.
The bit of code I'm using is based on a Unitronics example which I've tried to adapt for a V430 and I'm using VisiLogic 9.8.65
If anyone could give suggestions as to what I'm missing here it would be much appreciated.
Best Regards
Rob

Hi Joe
..still no success with a direct PC-PLC X-over connection where Win10 ipconfig (ethernet adaptor) = 169.254.17.247, 255.255.0.0, and no firewall and Project Settings are: V700P3, 169.254.17.150, TCP, 20256, V700P3
From PC pinging the PLC with 169.254.17.150 returns OK.
No success when I forced MB2 = 1 from within Visilogic
Network 5 results in MI20 = 34
Network 6 results in MI21 = 23
Hope you can help.
