Ewon Reboot

Ewon Support Ewon Flexy
#1

Hi Service Team !

I have a problem with a ewon with firmware 14.2s0 and 14.3s0PR

Scenario:
My machine has 4 Siemens S7-300 plc and ewon read tags from one plc only.
On ewon i have a BasicScript that enable/disable the IOServer when the plc is/isn’t running;
here the two functions called via Onchange event:

Function EnableIOServer()
LOGEVENT “EnableIOServer”, 10
SETSYS SYS, “load”
SETSYS SYS,“IOSrvData1:EnabledB”,“1”
SETSYS SYS,“IOSrvData1:EnabledC”,“1”
SETSYS SYS,“save”
LOGEVENT “IO-SERVER Enabled”, 10
ENDFN

Function DisableIOServer()
LOGEVENT "DisableIOServer IN ", 10
SETSYS SYS, “load”
SETSYS SYS,“IOSrvData1:EnabledB”,“0”
SETSYS SYS,“IOSrvData1:EnabledC”,“0”
SETSYS SYS,“save”
LOGEVENT “IO-SERVER Disabled”, 10
ENDFN

Now the problem:
when the basic script execute the instruction SETSYS SYS,“save” , in the BasicScript page i have this situation:
immagine
the “Abort execution” and “Pause execution” icons are enabled;

after a while, the ewon Reboot and in the event log i have this:
immagine

Workaround:

  • if i disable (//) the instruction SETSYS SYS,“save” , the script run without problems;

  • when the BasicScript has the two icon enabled (Abort and Pause) , if i disconnect from the net two plc, the script continue running;

  • if i connect the ewon with the plc only and disconnect from the net all other 3 plc, i have no problems;

  • i tried to increase the “Default TCP RX/TX Timeout” parameter to 5000 Msec but without any differences

If you need more info i can provide you

thanks

Hi service Team!

Hi @iw3bti1,

Do you mean that when you run this code that it causes the device to reboot immediately?

-Tim

#5

Can you send me a backup.tar file of this device with the support files included?

#6

not immediately, the ewon reboot after 3 minutes and in this 3 minutes the two buttons in the BasicScript page remain enabled as shown in the picture

#7

I see, would you be able to get a backup.tar file of the device with support files included for me to take a look at?

#8

ok i send you the .tar via message

#9

Does the device seem to be still having these issues if you comment out the function that disables the IO servers?

#11

like described in the first post:
if i disable (//) the instruction SETSYS SYS,“save” , the script run without problems;

#12

As an example, can you try and run those commands in the console and see if that causes a reboot as well?

#13

Yes, the result is the same

#14

Let me check with one of my colleagues on the development team, just disabling an IO server shouldn’t make a device reboot

#15

As described above, this script works on 200+ machines without problems. In this specific configuration i have 4 PLC on the same net. The problem isn’t disabling io server but the Setsys Sys , “save” instruction. If i disconnect 3 PLC on the net , the script works

#16

Sorry do you mean that if you disconnect 3 devices so it’s just talking to one device, or do you mean that you’re disabling a PLC so that you’re talking with 3 devices. There shouldn’t be an issue reaching 3 devices.

There also shouldn’t be any issue with reaching 4 devices if you define them at the tag level instead of at the IO server like it seems like you’ve done in your backup file

#17

Excuse me, my english is not so good :wink:

The machine network has 4 PLC, ewon talk with one plc only;

if all 4 plc are connected on the machine network, when the script execute the SETSYS SYS,“save” , in the Basic script button command i have the “Abort execution” and “Pause execution” and after a while the ewon reboot for watchdog in process (scp);

if all 4 plc are connected on the machine network and when the script execute the SETSYS SYS,“save” i disconnect at least 2 plc from the machine net before the watchdog time, the script run without problems.

#18

Have you tried changing the basic script to split the load and save for the IO servers?

Function EnableIOServer()
LOGEVENT “EnableIOServer”, 10
SETSYS SYS, “load”
SETSYS SYS,“IOSrvData1:EnabledB”,“1”
SETSYS SYS,“save”
SETSYS SYS, “load”
SETSYS SYS,“IOSrvData1:EnabledC”,“1”
SETSYS SYS,“save”
LOGEVENT “IO-SERVER Enabled”, 10
ENDFN

Hi @iw3bti1,

Were you able to try Ted’s suggestion to see if that worked for you?

-Tim

#20

on monday next week i’ll try

#21

Ok let me know what you find out

#22

hi i have tested the Ted’s suggestion but the result is the same;
the script stop running on the first SETSYS SYS,“save” instruction
