Transfer restrictions when using Siemens Moby I

[Borte]

Hello!

I wonder if someone here is familiar with the Simens Moby I (RFID)system?

I'm trying to write 50 bytes to an MDS403 (8Kb) memory tag over an ASM450 unit controlled from a 316DP2 CPU, but so far it only allowes me to transfer 30 bytes. As soon as I pass that limit it'll report the following error:

-> Input or output areas are too small for the telegram length used.
-> Read or write command with excessive length used
-> Adjust bus configuration of the master module.

I have used the same system with the same code to read / write 50 bytes of data before, the only difference was that I used a 413 CPU in that application.

Anyone have som toughts about this?

Regards
Borte
