Trying to write to LOGO BM modul through CMR2020

Hello

I'm working with SMS writing/reading with CMR2020 modul. i can easily write to both outputs on CMR2020 module. Reading from CMR2020 and BM is also fine.

The problem comes when i try to write to LOGO! BM.

in the CMR2020 manual, it says;

"Only the first 128 bytes of the BM variables memory can be read and written to".

The default VM-adresses for flags, and outputs, are 800+, so its way over the first 128 bytes.

The question here is, how can i change the default VM-adresses, so i can write to BM?

Already tried ->Tools->Parameter VM Mapping - but it only let me put a VM-adress for amplifier/tresholders/counters, maybe because the flags/IO already have assigned VM-adresses. (they are found in help->Contents->Parameter VM Mapping)

Thanks for your time

Hello,

When you use a Network input, you can declare the V address

Thanks for reply

I now created a NI1 (Address VM0,0) and NQ1 (Adress VM1,0).

When i text, i write -> "LOGO=VM1.0,1,BYTE"

The reply is "LOGO=VM1.0,1,BYTE: No Success".

Same goes for the NI1. 

It seems i can't read or write to the VM from logo. 

Does it have something to do with the network I/O is a "local", and there for can't be read by CMR2020?

Is it required the VM to be in the Parameter VM Mapping, or?

Thanks for your help

 Hello,

You have created a Network input VM0,0

So you can write to VB0, byte

(You can only write a byte, so this will be 8 booleans,  VB0 -> VM0.0 .. VM0.7)

You have created a Network output VM1,0

So you can read VB1, byte

(You can only read a byte, so this will be 8 booleans, VM1.0 .. VM1.7 -> VB1)

Perhaps you can try this.

It gives the same answer:

i write -> LOGO=VM1,1,BYTE

i recieve -> LOGO=VM1,1,BYTE: No Success

The firmware for CMR2020 is V2.1.5

Firmware for LOGO! 6ED1052-1MD08-0BA0 is 1.82.01

I'm entering the CMR on webpage, by its IP address.

i can change the password in -> WAN-> SMS-> "Password for writing commands". i unchecked the box named "Enable SMS password", so i guess you can write without password. Now i checked the box, and made the password 123 so, same still happends.

Now i'm sending "123;LOGO=VM15,1,BYTE

Answer is "LOGO=VM15,1BYTE: No Success"

The VM is a NQ, in my program, i havent configuered anything beside dragging it and change address. is it a problem, its a local VM Address?

How would you make a VM for an output, in LOGO BM?

Can it be the firmware? 

Still gives the same answer. 

I attached a picture of the address.

Somehow it feels like it can't connect. The "no success" means in CMR2020 manual, Values could not be set or read ". so i guess the connection is fine, but the VM is not?

Thanks for helping.

Hello,

So you write to address vb10?

First one is writing to CMR2020 modules Output, and it works fine.

Second is to logo, and ain't

Yes, i've read the chapter 4.2 and more.

i dont see the difference than the manual for CMR2020.

as i understand, i dont need to make any actions, events, or assingsments for writing to a VM, am i correct? its only for read/SMS/alarms.

The two pictures i attached in the previues messages, shows how i addressed a VM, and trying to write to it.

EDIT: You're completely right. what i thought i didnt have to, i DID have to. Thank you so much for great support.

yes it is. I didnt think it was nessesary to write the VM-address in Monitoring-> signals - to write to it, only for read. Now i've learned i'm wrong :) apparenty i'm not that good reading manuals as i thought.

Have a nice day
