Remote instructions

The following table lists the instructions used for transient transmission to the remote station.
Instruction Description
*1
REMFR Reads data in units of words from the buffer memory in the remote station. (16-bit address specification)
*1
REMFRD Reads data in units of words from the buffer memory in the remote station. (32-bit address specification)
*1
REMFRIP Reads data in units of words from the buffer memory in the remote station. (Target station IP address specification) (16-bit address
specification)
*1
REMFRDIP Reads data in units of words from the buffer memory in the remote station. (Target station IP address specification) (32-bit address
specification)
*2
REMTO Writes data in units of words to the buffer memory in the remote station. (16-bit address specification)
*2
REMTOD Writes data in units of words to the buffer memory in the remote station. (32-bit address specification)
*2
REMTOIP Writes data in units of words to the buffer memory in the remote station. (Target station IP address specification) (16-bit address specification)
*2
REMTODIP Writes data in units of words to the buffer memory in the remote station. (Target station IP address specification) (32-bit address specification)
*1 Firmware version "04" or later: When "Communication Mode" is set to "Multicast", the instruction can be executed on the master and
local station. When "Communication Mode" is set to "Unicast", the instruction cannot be executed on the local station.
Firmware version "03" or earlier: The instruction cannot be executed on the local station. Execute it on the master station.
*2 The instruction cannot be executed on the local station. Execute it on the master station.
Transient transmission ranges
In a single network system, communication with the remote station on the network is possible.
Communication is not available with stations in other networks.
Precautions
When using the REMFR, REMTO, REMFRD, or REMTOD instructions, configure an interlock with the following module
labels.
• 'Data link error status of own station' (SB0049)
• 'Data link status of each station' (SW00B0 to SW00B7) of the target station
Check that the data link status is normal. ('Data link error status of own station' (SB0049) and 'Data link status of each station'
(SW00B0 to SW00B7) of the target station are off.)

SLMP communication instruction

The following table lists the dedicated instruction used to send an SLMP frame to an SLMP-compatible device in the same
network.
Instruction Description
SLMPSND Send an SLMP message to the SLMP-compatible device in the same network.

Other dedicated instructions

The following table lists the dedicated instructions used to set parameters for the RJ71GN11-T2 of the own station.
Instruction Description
CCPASET Set the parameter in the RJ71GN11-T2. (Only partial parameters)
CCPASETX Set the parameter in the RJ71GN11-T2.
UINI Set the IP address to the own station for which the station number and IP address are not set.
Transient transmission ranges
Access to the RJ71GN11-T2 of the own station only is possible.
