Remote instructions

The following table lists the instructions used for transient transmission to the remote station.
When the version of Add-on baseSystem is "1.22" or earlier remote instructions are not supported.
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)
*1
REMTO Writes data in units of words to the buffer memory in the remote station. (16-bit address specification)
*1
REMTOD Writes data in units of words to the buffer memory in the remote station. (32-bit address specification)
*1
REMTOIP Writes data in units of words to the buffer memory in the remote station. (Target station IP address specification) (16-bit address specification)
*1
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 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
devices.
• '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.)
