[Data Table Write Speed]

storing data to datatable goes "instantly"

but storing datatable to sd card takes a few seconds.

[canopen vs a Cavotec remote control display]

I found a way to fix all my problems.

got some help from friend, a C(++) programmer .

to split a four digit number i had to use the MOD% command first then DIV

1234 DIV 1000= 1

1234 (MOD 1000) DIV 100 = 2

1234 (MOD 100) DIV 10 = 3

1234(MOD 10) =4

this can be good to use on 7segment displays i think.

when u want 4 digit number spit over 4pieces of 7segment displays

If you need it as number then you can divide the number by 1000 then 100 and 10 and put the resutls in 4 MIs.

cant find a way to split the digits.

ive tried with division in many different ways.. but if my MI is 1234. the first digit will store fine as 1.

but the second devided with 100 will be 12 i want 2. and the third divided by 10 will be 123 i want 3

this is how i want the result if= MI 1234 store 1 to MI 2

store 2 to MI 3

store 3 to MI 4

store 4 to MI 5

MI 1 is a value that goes up to 9999 and down back to 0

tanks for feedback. i read through the help file from Cavotec. at first it didnt tell me anything. it was just lika a foreign language.

but i have gotten an example file from our suppliers of Unitronics plc's.

I went through the file up and down back and forth many times. trying to understand the example file

when i then read through the file from Cavotec again i found this :

--------------------------------------

Sub-Index 001

Description Downlink Byte 1

Entry Category Optional

Data Type UNSIGNED8

Access RWW

PDO Mapping Yes

Default Value 0x0

to

Sub-Index 088

Description Downlink Byte 88

Entry Category Optional

Data Type UNSIGNED8

Access RWW

PDO Mapping Yes

Default Value 0x0

-----------------------------------------

the important thing i found here was the line - Data Type UNSIGNED8

that means its just regular numbers i need to send.

i then made a INCREMENT loop and Download STR. and i got it. my display is updating the Subindex i choosen. and goes through the whole list of characters, the dispaly can show.

now ill just divide my MI with 1000, 100 ,10 as Ofir mentioned

[canopen vs a Cavotec remote control display]

I have a V130plc v/canopen communication to a Cavotec remotecontroller.

the canopen config is done and working . i got remote IO's working too. send and receiving with SDO upload/download STR.

my problem is to send text and a number from an MI to the display on the remote CAN device.

the remote diodes that are working got these setting : SDO object index =2003

SDO Subobject index=2

the display got one Subobject index for each character, from 3-34

how do i get a 4 digit value from an MI split up into 4 different MI, and then send each digit to their subobject indexes in the display?

or is there a easier way to send many digits split out to the subobject indexes?

[CanOpen - SDO transfer complete]

I'm using a Vision 130, talking CanOpen SDO messages to a Kollmorgen AKD drive.

My question is, is there a 'message complete' bit in the V130 unit that would be true when a message is complete? I can see the CanOpen Transfer In Progress bit (SB242) and the CanOpen Transfer Failed bit (SB243), but I don't see a bit that indicates that the message was successful and completed.

I am trying to sequence messages to the drive, but need to know that the previous message was completed successfully before I start the next message.

Thanks,

Dan

think this might be as easy as to add a coil, on the output on the right side of the SDO send block.

not sure if this is what u need.

[info about ex-rc1]

hi,

can someone give me the example file how to use a rc-ex1 ? in the new software release of vison, they are missing

I need to read analog io values and write analog io via the ex-rc1

The help file is very summary and the online lessons don't give me the right anwer.

here are samples attached for communication with ex-rc1

u got to download one file to the plc. and the other to the ex-rc1 device.

i got these files from support@unitronics.
