Description
The PLC transmits request 1 for the converter with slave address 1,
interface 1 and for the converter with slave address 3, interface 2 to the
®
MOVILINK module. The module transmits corresponding
®
MOVILINK telegrams via interfaces 1 and 2.
Slave 1 and slave 3 have responded correctly. The MOVILINK
module transmits response 1 to the PLC.
The PLC transmits request 1 for the converter with slave address 1,
interface 1 and for the converter with slave address 3, interface 2 to the
®
MOVILINK module. The module transmits the corresponding
®
MOVILINK telegrams via interfaces 1 and 2.
Slave 1 has responded correctly (however, slave 3 has not responded).
The module now transmits response 2 from slave 2 with a message of
type 6 to the PLC.
Because slave 3 has not responded, the module transmits return code 2
(timeout) with a message of type 9 to the PLC.
The PLC transmits request 3 for the converter with slave address 1,
interface 1 and for the drive with slave address 3, interface 2 to the
®
MOVILINK module. The module transmits the corresponding
®
MOVILINK telegrams via interfaces 1 and 2.
Slave 1 and slave 3 have responded correctly. The MOVILINK
module transmits response 3 to the PLC.
The PLC transmits request 4 for the converter with slave address 1,
interface 1 and for the converter with slave address 3, interface 2 to the
®
MOVILINK module. The module transmits the corresponding
®
MOVILINK telegrams via interfaces 1 and 2.
Slave 1 has not responded. The module transmits return code 2
(timeout) with a message of type 9 to the PLC.
Slave 3 has not responded. The module transmits return code 2
(timeout) with a message of type 9 to the PLC.
