Uses of the CP 341
The CP 341 communication processor enables a point-to-point connection with various
Siemens modules and with non-Siemens products:
● SIMATIC S5 via the 3964(R) driver or RK 512 with corresponding interface module on S5
side
● Siemens PDA terminals from the ES 2 family via 3964(R) driver
● MOBY I (ASM 420/421, SIM), MOBY L (ASM 520) and ES 030K data acquisition terminal
via 3964R driver
● PCs via the 3964(R) procedure (the following development tools are available for
programming on PCs: PRODAVE DOS 64R (6ES5 897–2UD11) for MS-DOS,
PRODAVE WIN 64R
(6ES5 897-2VD01) for Windows or the ASCII driver)
● Barcode readers via the 3964(R) or ASCII driver
● Non-Siemens PLCs via the 3964(R) driver, ASCII driver, or RK 512
● Other devices with simple protocol structures by means of appropriate protocol
adaptation with the ASCII driver
● Other devices that also have a 3964(R) driver or RK 512
● Printers (HP Deskjet, HP Laserjet, Postscript, Epson, IBM)
The CP 341 can also be operated in a distributed configuration using the ET 200M (IM153)
I/O device.
