The network module undergoes the addition of functions and specification changes by
version upgrade.
For checking of the function version of the network module, refer to Section 2.3.
(1) Compatibility with old models
When replacing a previous network module (function version A or B) with the one
of function version D, there is no need to change the parameters, programs, and
switch settings.
However, to use any function not available for a previous version, the parameters
and programs must be modified.
(2) Additional functions
The table below shows the functions added to function version B or later.
Description
Multiple CPU systems are supported.
The following link dedicated instructions were added:
• RRUN instruction (remote RUN instruction)
• RSTOP instruction (remote STOP instruction)
• RTMRD instruction (other station's clock data read instruction)
• RTMWR instruction (other station's clock data write instruction)
The data length of the following link dedicated instructions was
increased from 460 words to 960 words:
• SEND instruction
• RECV instruction
• RECVS instruction
• READ/SREAD instructions
• WRITE/SWRITE instructions
• The network module can be mounted on the base unit of the
redundant system and used (redundant network module).
• A system switching request is automatically issued to the control
system CPU in case of a data link error or malfunction.
In the following link dedicated instructions, the target station CPU
type can be designated (the redundant system's control
system/standby system and system A/B can be designated):
• READ/SREAD instructions
• WRITE/SWRITE instructions
• REQ instruction
• RRUN instruction
• RSTOP instruction
• RTMRD instruction
• RTMWR instruction
Compatibility with the MELSECNET/H Extended mode
(The maximum number of link points per station has been
increased from 2000 bytes to 35840 bytes)
In the following link dedicated instructions, the target station CPU
type can be specified. (The CPU No. in the multiple CPU system
can be specified.)
• READ/SREAD instruction
• WRITE/SWRITE instruction
• REQ instruction
