Program modification of Koyo Electronics PLC



I was asked to modify the program of the PLC made by Koyo Electronics.

Several types of PLC are in operation.

How should I select programming software, PC connection cable, etc.?



Currently, we have two types of programming software.

Both are compatible with Windows 10 32 / 64bit.

It can be downloaded free of charge from our website.

1.Koyo PLC Programming Software (kpp)

Please use kpp when handling the D2-263, SJ-ETHER series.

2.DirectSOFT5.1 (DS)

DirectSOFT has been used for a long time, but Build 034, which is currently being released, is the final version and will not be updated in the future.

Please use DirectSOFT when handling SA / SR series and SG-8 (B) programs that are not supported by kpp.
Please prepare the following products for the connection cable according to the CPU series.

SZ / D2 series, D0 series, SJ / SJ-ETHER series

Cable: Z-20JP
D sub 9-pin conversion connector: S-9CNS1

SU / D4 series, SG series




* E-03DM serial communication unit is also required.

It has already been abolished.

We have rental machines available, so please contact us if necessary.

The communication port of each CPU is the RS-232C serial port.

If your computer does not have a serial port, please prepare a commercially available USB-serial port conversion cable separately.
