Hardware version

where:

00 … 07 = hardware version
08 .. 15 = RD6 model equipped with the following interface: 0x10 = Modbus;

0x11   =   Profibus;   0x12   =   CANopen;   0x13   =   POWERLINK;   0x14   =
EtherCAT

Value   10   01   hex   in   hexadecimal   notation   corresponds   to   the   binary
representation  0001 0000 0000  0001 and  has to  be  interpreted as follows:
hardware version 1 (LSbyte = 0x01); RD6 model with Modbus interface (MSbyte
= 0x10).
