MODBUS Mapping for Write Bit Services FC5, FC15

The table below outlines the mapping for the MODBUS-writing, bit-oriented
services:
• FC5 – Write Single Coil
• FC15 – Write Multiple Coils

Table 207: MODBUS Mapping for Write Bit Services FC5, FC15

MODBUS Address
(hexadecimal values
in parentheses)
0 ... 6143
(0x0000 ... 0x17FF)
6144 ... 12287
(0x1800 ... 0x2FFF)
12288 ... 65535
(0x3000 ... 0xFFFF)
Draft version 1.2.1 from 2017-09-13, valid from FW Version 02.06.20(09)
IEC 61131 Description
Address
%IX1000.0 ... MODBUS Output:
%IX1383.15 6144 PFC input bit variables in the first
384 registers/words (768 bytes) of the
2kB MODBUS output process image in
the PII.
%QX1000.0 ... MODBUS Output:
%QX1383.15 MODBUS-only area for bit-oriented write
access.
Bit-based write services for this area are
acknowledged by the MODBUS slave
with the MODBUS exception code
"ILLEGAL DATA ADDRESS" (0x02).
%MX0.0 ... Maximum bit-addressable flag area:
%MX3327.15 53248 bit flags (6.5 kB);
the actual addressable flag area
depends on the current memory
arrangement in CODESYS.
