Switch Setting

The switches that determine the operation mode and node address are on the
front panel of the MD911 module.
The method to set the switches is shown below.
3.1.1 TC-net I/O bus address switch (I/O)
The TC-net I/O bus address switches are hexadecimal rotary switches that
determine the address on the TC-net I/O bus.
3.1.2 Station address setting switch (STN-H, STN-L)
The station address setting switches are hexadecimal rotary switches that
determine the node address on the MODBUS network.
For setting of the node address, refer to "3.2 Network parameter setting." Set the
station address (1 to 255) that has been assigned upon system configuration in a
HEX code. Assign an address with a different value to each of the stations in the
system.
Table 3-1 shows the setting of a station address.
Set the station address in hexadecimal.
For example, if the address value is 28, it is '1C' (h) when converted to
hexadecimal. Therefore, set as follows:
For decimal-hexadecimal conversion, refer to "Appendix D Decimal-hexadecimal
conversion table."
