206 JVL Industri Elektronik A/S - User Manual - Ethernet for MAC and MIS motors
8.3 Sercos Communication
The default last octet of the IP address is calculated from the last octet of the MAC ad-
dress printed on the sticker of the MAC Sercos
®
module or the Sercos
®
MIS/MIL motor.
For example if the MAC-ID of a JVL motor is: 54 : E3 : B0 : D0 : C9 : 14, then the IP
address is set to: 192.168.0.20. (The MAC address is in hexadecimal and the IP address
is in decimal, so converting the 14 from the MAC-ID from hexadecimal to decimal gives
20 in decimal). The IP address of every device in the network has to be unique, and the
first octets as indicated by the subnet mask have to be the same in devices that wish to
communicate. If the IP setup values are changed, by means of MacTalk then remember
to save the values in flash by pressing the “Apply and save” button after the values are
changed.
8.3.10 Accessing motor registers and Sercos
®
module registers
Besides all the standard IDN’s the JVL Sercos
®
module also support direct accessing of
all the native registers in the Sercos
®
communication module and in the MAC/MIS/MIL
motor controller. They are accessed over the service channel using the P IDN’s.
