Possible applications for the CP 340
The CP 340 communication processor supports point-to-point communication with various
Siemens modules and with non-Siemens products:
● SIMATIC S5 via the 3964(R) driver with corresponding interface module on S5 side
● Siemens BDE terminals ES 2 family via 3964(R) driver
● MOBY I (ASM 420/421, SIM), MOBY L (ASM 520) and ES 030K data acquisition terminal
● SIMOVERT and SIMOREG (USS protocol) via the ASCII driver (CP 340-RS 422/485),
● PCs via the 3964(R) procedure (the following development tools are available for
● Barcode readers via the 3964(R) or ASCII driver
● Non-Siemens PLCs via the 3964(R) or ASCII driver
● Other devices with simple protocol structures by means of appropriate protocol
● Other devices that also have a 3964(R) driver
