8.1 Communication protocol
The communication protocol of the MEMMERT P-controller was defined following the rules
of the association for standards for measurement technology and control engineering in
the chemical industry (NAMUR).
8.2 Computer connection
For linking your P-appliance to your PC there is an
interface connector on the back of the casing of every
unit.
The oven can be linked to the PC using a shielded
interface lead to the connector. If a different lead is used,
care must be taken to use a shielded interface lead. The
shielding must be connected to the plug casing.
If the serial port is not used, the plug must be protected
with the protection cap.
8.3 Interface RS232C
The P-unit is equipped as a standard feature with an RS232C interface according to DIN
12900-1. With this interface it is possible to operate the oven from a PC. This is done with
the aid of the „CELSIUS 2000“ software program. In the submenu SETUP the oven must
be allocated an address in the menu item ADRES. The PC then communicates with the
oven using this address. The standard setting is ADR00.
Should more than one unit be linked to one PC via an RS232C interface, then each unit
requires an appropriate interface on the PC and a separate lead.
The maximum length of one lead is 15 m.
Example:
Three ovens linked to one PC via RS232C.
