Parameters 241
Slot 3 An FMBA module installed in JCU option slot 3 is used. 3
58
58 Embedded Modbus
Configuration parameters for the embedded fieldbus (EFB)
interface. See also chapter Control through the embedded
fieldbus interface on page 311.
58.01 Protocol ena sel Enables/disables the embedded fieldbus communication
protocol.
Note: When the embedded fieldbus interface is enabled, the
drive-to-drive link operation (parameter group 57) is
automatically disabled.
Disabled Disabled. 0
Modbus RTU Modbus RTU protocol enabled. 1
58.03 Node address Defines the node address.
0…247 Node address. 1 = 1
58.04 Baud rate Selects the baud rate of the RS-485 link.
4800 4.8 kbit/s. 0
9600 9.6 kbit/s. 1
19200 19.2 kbit/s. 2
38400 38.4 kbit/s. 3
57600 57.6 kbit/s. 4
76800 76.8 kbit/s. 5
115200 115.2 kbit/s. 6
58.05 Parity Selects the number of the data bits, the use and type of the
parity bit, and the number of the stop bits.
8 none 1 Eight data bits, no parity bit, one stop bit. 0
8 none 2 Eight data bits, no parity bit, two stop bits. 1
8 even 1 Eight data bits, even parity bit, one stop bit. 2
8 odd 1 Eight data bits, odd parity bit, one stop bit. 3
58.06 Control profile Selects the communication profile used by the Modbus
protocol.
ABB Classic ABB Drives profile, classic version. 0
ABB Enhanced ABB Drives profile, enhanced version. 1
DCU 16-bit DCU 16-bit profile. 2
DCU 32-bit DCU 32-bit profile. 3
58.07 Comm loss t out Defines the timeout limit for EFB communication loss
monitoring. If a communication break exceeds the timeout
limit, the function proceeds with the action defined with
parameter 58.09 Comm loss action. See also parameter
58.08 Comm loss mode.
0…60000 ms Timeout calculation factor. The actual timeout value is
calculated as follows:
Comm loss timeout × 100 ms
Example: If you set this value to 22, the actual timeout value
will be: 22 × 100 ms = 2 200 ms.
100 = 1 ms
58.08 Comm loss mode Enables/disables EFB communication loss monitoring and
defines which of the Modbus register accesses resets the
timeout counter. See parameter 58.07 Comm loss t out.
