FPΣ (Sigma)
Supports the enhancement of your equipment’s performance
Network enhancement
Modbus-compatible
FP
Σ (Sigma) is compatible with the world's
de facto standard Modbus* and can serve
as both Modbus RTU master and slave,
making it ideal for air conditioning or
temperature control etc.
* Protocol developed by Modicon Inc., an American company
These applications are also available.
When 17 or more FP
Σ (Sigma) units need to be
linked, you can use the Modbus function instead
of MEWNET-W0 to link up to 99 units. Since each
FP
Σ (Sigma) unit can be either a master or a slave,
a multi-master link can be created by passing a
token from a user program.
Security enhancement
Programs are copy-protected by the upload restriction setting and an eight-character password.
The setting to inhibit the uploading of PLC programs to PCs protects your programs from unauthorized
copying. (If this setting is released, programs in the PLC are forcibly cleared.)
An eight-character password has been adopted. (The conventional four-character password is also available.)
Approx. 218 trillion passwords can be set by combining eight alphanumeric characters, making it nearly
impossible to crack the password set.
Debugging performance enhancement
Up to 512 steps can be rewritten simultaneously in RUN mode.
This improvement allows efficient program debugging without stopping the operation.
New “MEWTOCOL Master” function is available.
The MEWTOCOL master function automatically creates and transmits commands using the Panasonic open
protocol MEWTOCOL. This function significantly facilitates serial communications with MEWTOCOL-
compatible equipment, such as PD50, KT4H and KW4M.
