Server Map
The
Server Map
page sets up the register map for a virtual Modbus/TCP server, allowing a custom
view of remote registers.
Use the
Server Map
page to set up a copy of various remote register data to a specific, unused
Modbus registers. For example, copy the data in register 8 from all devices to a Modbus register
block. This map is also referred to as the user map.
Bit Field and Fill: Defining the Bit field allows the compiling of register contents derived from
multiple sources. The source data is limited to the number of bits represented in the bit field (a
hexadecimal value) and is shifted into the position represented by ‘1’ bits in the field.
Fill bits are logically OR’ed into the result before the server presents the data. Consecutive server
map entries that reference the same server address are OR’ed together and presented at that
address. Duplicate map entries referencing the same server address but not listed in consecutive
order following the first instance are skipped. No special bit field processing occurs if the bit field is
set to zero. Bit fields apply to 16-bit integer or unsigned integer server registers only.
For example, a bit field entered as 00FF indicates a need for eight bits of the Local Register,
mapped to the lower portion of the Mapped Register Number. A bit field of FF00 still indicates a
need for the lower 8 bits of the Local Register, but mapped to the upper portion of the Mapped
Register Number. For example:
Local Register Contents
Bit Field
Result copied to Mapped Register
005A
0FF0
05A0
005A
F0F0
00A0
005A
00FF
005A
005A
FF00
5A00
1234
0F0F
0204
