R200, R200P, COM2-E Communication Modules
The COM2-E provides two interfaces:
D Ethernet interface (10BaseT)
D V.24 / 20mA combination interface
Both interfaces can be operated simultaneously, and each interface features
its own 7-segment for status indication.
The COM2-E supports the following transmission protocols:
D TFTP protocol (Trivial File Transfer Protocol)
D BUEP-E
D BUEP19E
D BUEP3E
D BUEP64.
The TFTP protocol (Trivial File Transfer Protocol), specified in accordance
with RFC782 dated 1992, provides a PC host computer or UNIX workstation
with a simple means of communicating with the controller. Data fields up to
510 bytes in size can be loaded from the controller. Larger fields are not sup-
ported. Also, write access to data fields is not available due to security consi-
derations.
BUEP-E is the designation of a protocol used for communication via Ether-
net LAN. With regard to the user interface, and with the exception of the IP
address and the error codes, BUEP-E is identical to the BUEP19E protocol.
The BUEP19E protocol conforms to the DIN 66 019 standard. It controls the
data traffic handled via serial interface between programmable memory
controllers and peripheral devices. The data interchange transactions are
protected against loss of data.
The BUEP03E protocol is a simple ASCII protocol for data transmission via
serial interface between programmable memory controllers and peripheral
devices.
The BUEP64 protocol is used to handle the data exchange between com-
plex or spatially distributed controller systems.
On the basis of the listed transmission protocols, the COM2-E provides the
following connectivity options:
D Computer (PC, host computer, etc.)
D CL150, CL200, CL400, CL500
