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
