how can i Connecting AC800M(Compact) with DCS800
How can i read/write (Data/Command)from an AC800M Compact to DSC800 using , is thier any special steps need to be taked like activating some drive parameters to enable such function ? ... kindly advice

You can connect DCS800 drive to AC 800M via CI858 module over drive bus, yes you need to configure/activate some drive parameters. You can find drive parameters settings in DSC800 Firmware manuals 3ADW000193. I am not expert with drives but trying to extend information to you.
Hope it helps to you..
For Drive bus communication with AC800M you need to insert SDCS-COM-8 card on DCS800 drive. Also DCS800 support the following communication protocols,
–– PROFIBUS-DP +K454
–– DeviceNet +K451
–– CANopen +K457
–– ControlNet +K462
–– Modbus +K458
–– Ethernet +K466
accordingly you need to select the CI module in AC800M plc,
Yes you need to configure the parameters based on your communication module,
Eg: for Modbus configure Group52,98
for Fieldbus configure Group51,98
for Drivebus configure Group70,71
To Communicate AC800M with the DCS800 Drive Via., DriveBus. The Hardware components required are CI858 Module (AC800M) , SDCS-COM-81 module (DCS800) & Plastic Fibre optical cable(<10m).
a) Communication Parameter Settings in Drive Side as follows:
Parameter Number Setting
1) 98.02 = 'COM-8/AC800x'
2) 70.01 = '1 ' (Node Number)
3) 70.24 = 10
4) 71.01 = Yes
5) 10.01 = MainCtrlWord
6) 11.03 = SpeedRef2301
7) 50.01 = SpeedMax (Speed Scaling Need to Set)
Data From AC800M to DCS800.
8) 90.01 = 701 (Main Control Word)
9) 90.02 = 2301 (Speed Ref)
Data From DCS800 to AC800M.
10) 92.01 = 801 (Main Status Word)
11) 92.02 = 104 (Speed Act)
12) 92.03 = 108 (Motor Torque %)
13) 92.04 = 901 (Fault Word1)
b) Settings in AC800M.
'CI858DriveBusHwLib' = Hardware Library need to Insert in the project.
Insert " CI858" in the Hardware Structure, & then Insert "0-Drive Channel',
Insert "1 ABB Engineered Drive".
Settings for CI858 & Drive Channel - keep default values.
Settings For ABB Engineered Drive "Settings TAB' as follows.
1) DataSet10 Config Status = Read/Write
2) DataSet12Config Sattus = Read/Write.
Connect the Hardware signals in the "Connection TAb".
DS11 Channel 1 = Main Status Word.
DS11 Channel 2 = Speed Ref
DS10 Channel 1 = Main Control Word.
DS10 Channel 2 = Speed Act
DS10 Channel 3 = Motor Torque.
DS12 Channel 1 = Fault Word1.
Main Control Word Should be as per following Sequence.
1142 = Drive in Remote & No Emergency Stop.
1143 = Drive Armature Contactor & Field On.
1151 = Drive Run Cmd.
Then Release the Speed Reference.
Speed Scaling in the AC800 M Software (+20,000 = Speed max in r.p.m Forward Dir)
(-20,000 = Speed Max in r.p.m Reverse Dir)
Torque Scaling in the AC800M (100 = 1%)
Hope above info will be useful to u.
You can conect ABB Drive via:
- DriveBus Interface CI858.
- PROFIBUS DP Interface CI854 (Need the PROFIBUS DP Card of the Drive).
- PROFIBUS DP Interface CI854 and CI801 (Do not need the PROFIBUS DP Card of the Drive).
- PROFINET IO and CI871.
But the cheapest and easiest way is use MODULEBUS, this give some advantage:
1.- Don't need any adicional comunication interface.
2.- You can access to the some pre engineering elements.
In single CPU configuration, ABB Drives can be connected to the processor unit via the optical ModuleBus. See Figure. The number of ABB Drives which can be connected to the optical ModuleBus, can be described by the following equation:
(No. of ABB Drives) < 84 - (12 x (No. of TB820s))
That is, each Drive uses one ModuleBus cluster.
