Compact HMI 800 communicating AC500eco
Hi, Is possible to communicate the Compact HMI 800 V5.1 with the PLC AC500 eco?
The operating systems is Windows 7 Proffesional English 32bits.
What Version of ABB configurator do I need?
Can I use other OPC Server for Modbus TCP, like Kepware?
When I install the compact HMI 800, an OPC server is installed too. This one have a modbus TCP driver?
Thanks for your help.

Compact HMI can be used to communicate with AC500PLC. For this you may install the AC500 Control Builder and OPC server on the server node to use Compact HMI 800 with AC500.
It is recommended to use the ModBus TCP driver in the Compact HMI 800 to access the AC 500 controllers.
Hope this will help you..
for Comapct HMI could be as AC500 PLC 's SCADA. but you should install OPC Server for AC500 PLC_WinCoDeSysOPC software. and in Comapct HMI side, using PLC Generic Control Network and choose CoDeSysOPC as protocal.
When you install Comapct HMI, one OPC for AC800M has been automatically installed with Compact HMI, but this OPC is for AC800M controller , not for AC500 PLC. If in your project , you do not use AC800M Controller, you could not remove it.
Thanks for your comments. I have other question.
In the compact hmi 800 I can see a modbus tcp driver. I'm using this one for communicate with the Ac500eco and this found very well with integer an boolean tags.
For example: When I point to a bit address I use C0001 and for the Holding registers I use HR0001.
But I have problems reading a real value, because it is showed its integer value I supouse because I'm using the same address (a holding register like HR0001).
Do you know how do I have to point to a float address, because these values consist of two holding registers.
Thanks for your help.
OPC communication is the better way to communicate the Compact HMI 800 V5.1 & the PLC AC500 eco.
Use PS501 Control Builder V2.1 software and the Codesys OPC server. This Version is well supported in the Windows 7 32 Bit.
Using the OPC communication gives you benefits like direct access to the REAL, TIME DINT etc.. datatypes and the memory consumption of the PLC will be less when compared to the Moddus TCP/IP.
For conectivity with Compact HMI 800 with Eco PLC My Answer is same as mentioned above , for your new Question
you can follow following scheme in order to read real values from eco PLC to Compact HMI.
At compact HMI : HRA199,REAL
Equivalent Address at Eco PLC: %MD0.100
