CI858 drivebus to ACS880 with FDCO-01

Hi,
Problem to get DDCS communication working.
Have one ACS880 single drive with FDCO-01 module. In other end AC800M with CI858 module.
Have setup ACS parm group 60, 61 and 62 for DDCS engineered drive. And corresponding dataset in CI858.
Have FDCO in slot 1, fibre in chA so I guess 60.51 = Slot 1A
60.52 Node address = 1, same CI858 number in control builder.
Have set 60.55 = Star...have fibre direct from CI858 to FDCO.

I can see Tx/Rx led at 858 sporadic flash. But ACS say DDCS error and CI858 have "red triangles" at configured datasets. Have "swooped" POF fibre without any success.

Is NDBU-85 Branching unit need for POF fiber between FDCO and CI858? Or is it possible to connect directly. I only have one drive in my network.

//Henrik

Could You please attach the list of parameters for FDCO Drive; and Also indicate the Node Address in the PLC and Drive End?

Also Please attach the screen shot of the configuration.

And there is NO Need for NDBU-85 for POF between FDCO and CI858.

I have attached a Screen shot of group 60 of a drive that I did for commissioing; please check the parameters 60.52: Node Address and share the pic of your Configuration in Control Builder.

In addition to post of rajul1230 , see example of working setting of ACS880 Engineered drive in CBM under CI858 with DDCS address=2 :

USE_BUSMANAGER = 0 = Use BusManager
APPL_ID_ADDR = 9910 = Address of Application ID in Drive
APPL_ID = 2 = Configured Application ID -> this parameter shall match drive's address
CONF_APPL_ID_DATA_TYPE = No Checking = Configured Application ID data type
DRIVETYPE_ADDRESS_IN_DRIVE = 401 = Address of drive type in drive
DRIVE_TYPE = AMXG6040 = Drive Type
DRIVE_TYPE_CHECK_MASK = ???????? = Drive Type Checking Mask
DATASET1_STATUS = Read/Write = Dataset 10 config status
DATASET2_STATUS = Read = Dataset 12 config status
DATASET3_STATUS = Read = Dataset 14 config status
DATASET4_STATUS = Read = Dataset 16 config status
DATASET5_STATUS = Read = Dataset 18 config status
DATASET6_STATUS = Off = Dataset 20 config status
DATASET7_STATUS = Off = Dataset 22 config status
DATASET8_STATUS = Off = Dataset 24 config status
DATASET1_PRIORITY = High Prio = Dataset 10 Priority
DATASET2_PRIORITY = Normal Prio = Dataset 12 Priority
DATASET3_PRIORITY = Normal Prio = Dataset 14 Priority
DATASET4_PRIORITY = Normal Prio = Dataset 16 Priority
DATASET5_PRIORITY = Normal Prio = Dataset 18 Priority
DATASET6_PRIORITY = Normal Prio = Dataset 20 Priority
DATASET7_PRIORITY = Normal Prio = Dataset 22 Priority
DATASET8_PRIORITY = Normal Prio = Dataset 24 Priority

Also note that each dataset used should have at least 1 variable connected.

Other 2 peculiarities valid for DCS800 & CI858 in CBM version 5.0 (maybe still applied):
- reading & writing dataset variables shall be connected to the logic in the same AC800M task.
- numerical values exchanged with drive except Dataset 10 are interpreted without signum.
In other words values in range 32768-65535 received from drive shall be recalculated as negative numbers.
