Red Lion PAXCDC5 (PROFIBUS) - Manual

1
DESCRIPTION
The PAX PROFIBUS-DP Communications Option Card provides a direct
connection for a PAX panel meter to a PROFIBUS-DP Network. This allows a
PROFIBUS Master device, such as a PLC, to control and monitor the operation
of the PAX meter. The meter functions as an intelligent PROFIBUS-DP Slave
device on the Network.
The PROFIBUS-DP Network connects through a 9-pin D-subminiature
female connector on the rear of the card. The card is installed in the PAX meter
using a slotted rear cover, allowing the PROFIBUS-DP Connector to extend
beyond the rear of the PAX case. Power for the card is provided internally from
the power supply of the PAX meter. The PROFIBUS-DP Network is isolated
from the control electronics on the card using high-speed optocouplers.
This fully featured communications card supports Automatic Baud Rate
Detection, with an operating range of 9.6 Kbaud up to 12 Mbaud. The Station
Address is set via rotary switches. The card’s address is read at power up.

Data Exchange with the Master device occurs through cyclic I/O data
transmission. The size of the I/O data block is determined by the selection of
pre-configured Modules for the specific PAX meter type. All data values are in
32-bit integer format, Motorola byte ordering. The PROFIBUS-DP protocol per
EN 50170 is implemented using the Siemens SPC3 ASIC. Three on-board
Diagnostic LEDs indicate the status of Data Exchange (DATA), the SPC3
Watchdog (WD) and DP State Machine (DP).
PNO Conformance and GSD File
The PAX PROFIBUS-DP Card is PNO certified, having passed the
conformance test for PROFIBUS-DP Slave devices, Certificate No. Z01170.
The PNO Identifier for this PROFIBUS device is 0x09D0. The functional
characteristics are described in GSD file REDL09D0.GSD. The GSD file and
PAX bitmap can be downloaded from the Red Lion Controls website.
