Hello Mates,
first time developing with deviceNet, Im more used with S7 CPUs.
My system is a L23E CPU + PanelView 550 on devicenet.
I can't understand how to properly set the data mapping.
The HMI is getting reading shifted twice the address value.
Local:5:O.Data[2] on CPU is read on HMI as tag O:4
Local:5:O.Data[10] on CPU is read on HMI as tag O:20 the same for inputs.
I've set the deviceNet for 50 Words. So, a bunch of doubts:
#1 - devicenet is can based, which is has a payload of 8 bytes per message, should not everything being set in bytes?
#2 - I can't finde the EDS file for PV550 2711-K5A10 FW4.1 and newer
#3 - On logix5000 general tab of 1796-SDN input and output sizer are given in 32Bits words. For the panelBuilder in words (dont know if a 16 or 32 bit word). At rsnetworx for device I had to map as size 100, otherwise the scanned would give error 77 (Slave data Mismatch). Chaging the data alignment between pack/byte/word etc seems to have no changes in data packaging.
#4 - Adding the networx file (.dnt) in logix has any usefulness? All my changes have to be made in rsnetworx anyway.
greetings, Renan
