Complementary information
•
The module status bits have the following meanings:
°
0 = Error
°
1 = No error
•
If a module is not present, all bits of the module are set to logical 1.
•
Bits reserved for future use are always logical 1.
•
The status bytes of each module are transmitted as a 32-bit word in big endian
format, i.e. the most significant byte (MSB = byte 3) is transmitted first and the
least significant byte (LSB = byte 0) last.

Commands
The output data is written dynamically. From address 256, a client can, for example,
write 25 words (50 bytes) of output data. From address 257, 24 words (48 bytes) of
output data can be written, and so on.

SLMP
Overview
The safety controller supports an SLMP server without a safety protocol.
SLMP (Seamless Messaging Protocol) is used for communication in CC-Link systems.
SLMP allows you to read and write data ranges completely or only up to a smaller data
quantity (
≤
total size).
Supported commands
•
0x0613 Read memory
•
0x1613 Write memory
•
0x0E30 Node search
