MOVLNK
BusType (H+0)
Possible bus types:
ML_BT_S0 = 1 (RS485 #1)
ML_BT_S1 = 2 (RS485 #2)
ML_BT_SBUS1 = ML_BT_SBUS = 5
ML_BT_SBUS2 = 8
Address (H+1)
0...99: Single address
100...199: Group address
253: Address of the inverter
254: Point-to-point connection
255: Broadcast
If an SBus group address (e.g. 43) is addressed, the offset 100
must be added. In this case 143.
Format (H+2)
Specification of the process (PD) and parameter (PARAM) chan-
nels for data transfer:
//MoviLink Cyclic Frame Types
ML_FT_PAR1 = 0: PARAM+1PD
ML_FT_1 = 1: 1PD
ML_FT_PAR2 = 2: PARAM+2PD
ML_FT_2 = 3: 2PD
ML_FT_PAR3 = 4: PARAM+3PD
ML_FT_3 = 5: 3PD
ML_FT_PAR = 6: Parameter (without
PD)
//Acyclic
ML_CFT_PAR1 = 128
ML_CFT_1 = 129
ML_CFT_PAR2 = 130
ML_CFT_2 = 131
ML_CFT_PAR3 = 132
ML_CFT_3 = 133
ML_CFT_PAR = 134
Service (H+3)
Communication service for parameters
ML_S_RD = 1: Read service
ML_S_WR = 2: Write to non-volatile memory
ML_S_WRV = 3: Writing without saving
Index (H+4)
Index number of the parameter to be modified or read (see param-
eter index directory)
The subindex must be entered in the index element on bits 23-16
(least significant byte of the high word).
Calculation: H+4 or
MOVILNK.Index = Index + (SubIndex << 16);
DPointer (H+5)
Number of the variable from which the read data is stored or from
which the data to be written is obtained (structure MLDATA)
Result (H+6)
Contains the error code after the service has been performed or
contains zero if there was no error (see "Parameterization Return
Codes" in the "Communication and Fieldbus Unit Profile" manual
with "parameter list").
MLDATA
WritePar (H"+0)
Parameter that is sent for write services
ReadPar (H"+1)
Parameter that is sent for read services
PO1 (H"+2)
Process output data 1
PO2 (H"+3)
Process output data 2
PO3 (H"+4)
Process output data 3
PI1 (H"+5)
Process input data 1
PI2 (H"+6)
Process input data 2
PI3 (H"+7)
Process input data 3
