Sufficient programming capacity

32 k steps: Approx. 2.7 times bigger than our conventional model
More advanced and complex control is required for PLCs in accordance with equipment functionality enhancements, such as the support of multi-axial positioning, multi-point temperature control, serial communications, or networking. A greater programming memory capacity is thus being increasingly required, even for compact models. FPΣ V3 has a programming capacity of 32 k steps, which is approx. 2.7 times bigger than our conventional model and can accommodate an increase in the number and complexity of programs without difficulty.

High-speed operation

0.32 μsec/step for basic instructions:
Approx. 1.2 times faster than our conventional model
Upgraded equipment also requires an increase in the operation speed of PLCs to process increased programs in addition to the expansion of the program memory. FPΣ V3 is compact in size but equipped with a RISC processor. The basic instruction operation speed is 0.32 µs/step, which is 1.2 times faster than our conventional model. The speed of high-level instruction operations, including floating point operations, is also high, reducing the total scan time.

Simple temperature control

New PID instruction (F356 EZPID) has been added.

• Temperature control applications operated by PLCs are being expanded, for example, to multistage control, timer control, control according to variables based on data processing results, or multipoint control. FPΣ V3 has a new PID instruction (F356 EZPID), which makes PID control programming much easier than with our conventional model, facilitating temperature control by a PLC, which had previously been considered difficult. The right-hand example shows simple temperature control. A combination of touch panel operations and the F356 instruction allows you to write the program in only one line, significantly facilitating PID control.

Control data can be seen at a glance.

• Since key parameters are written in each instruction line, you can see details of the PID control at a glance by monitoring instructions on the ladder program.

Network enhancement

Modbus Master/MEWTOCOL Master/3-port generalpurpose serial communications

Modbus-compatible
FPΣ V3 is compatible with the world’s Modbus* de facto standard and can serve as both Modbus master and slave RTUs, which are 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 FPΣ units need to be linked, you can use the Modbus function instead of MEWNET-W0 to link up to 99 units. Since each FPΣ unit can be either a master or a slave, a multi-master link can be created by passing a token from a user program.

The new “MEWTOCOL Master” function is available.
The MEWTOCOL maste

r function automatically creates and transmits commands using the Matsushita open protocol MEWTOCOL. This function significantly facilitates serial communications with MEWTOCOL-compatible equipment, such as PD50, KT4H, and KW4H.

Up to 3 general-purpose serial communication ports can be used at once.
In addition to COM1 and COM2 of a communication cassette, the tool port also became usable as a generalpurpose serial port in the RUN mode. This new feature increases the number of devices that can be connected simultaneously, such as barcode readers, printers, meters, RF-ID, and wireless equipment.

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. (Tne 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 set password.

Debugging performance enhancement

512 steps rewritable in RUN mode
Up to 512 steps can be rewritten simultaneously in RUN mode. The number of steps is four times larger than with the conventional model. This improvement allows efficient program debugging without stopping the equipment operation.
