41) Station ID - When using the WP20’s serial communication features with multiple scales,
each scale must have a unique Station ID (or address). Station ID’s are designated A through P.
Select a different station ID from A to P for each scale. Normally the WP20 is Station A.
42) Parity - When using the WP20’s serial communication features, select the same parity as
the remotely connected communications device. The selections are None, Odd, or Even.
43) Baud Rate – When using the WP20’s serial communications features, select the same
Baud Rate as the remotely connected communications device. The selections are: 300, 600,
1200, 2400, 4800, 9600, or 19200.
44) Command Menu - The WP20 can send data to a remote device via the serial port, either
automatically (every 1/10
th
second) or upon request (manually). If it’s to be done automatically,
the desired data must be pre-selected using the Command Menu listed in Section 8.02
(Commands 01 through 22). If a remote device will request that data be sent, the Command
Menu must be set to 00 (manual). Refer to Section 8.03 for details on how to remotely request
data from the WP20.
45) Protocol Menu – When making a remote request for data from the WP20 via the serial
port, there are two different Tecweigh Protocols that can be used. The selections are Tec Std and
Tec Old. Tec Std provides more secure communications, and Tec Old provides historical
commands for older processors. New users should use Tec Std, and older existing installations
should use Tec Old. The request for data formats are the same for either protocol. Refer to
Section 8.04 for further details.
Field-bus Protocol Cards
The following four commands will only appear in the Parameter table if there is a field-bus
protocol card installed in the Anybus header located next to the MP400 display board ribbon
cable header. These individual and separately installed cards allow communications using the
Modbus, Profibus, Ethernet, DeviceNet, or A-B Remote I/O communications protocols.
46) Data Type – The numerical information within the field-bus protocol card will always be
32 bits of data, but is selectable between integer and floating point. The selections are:
Long – 32 bit long integer.
Float – 32 bit floating point.
47) IP – Used for the Field-bus interface card for identifying the processor’s IP address.
48) IM – Used for the field-bus interface card for identifying the processor’s IP mask if
utilized.
49) I/O Rack – Used only for the A-B Remote I/O field-bus interface card for identifying the
processor’s memory utilization.
50) Lock Aut Zr - Select YES to protect the AUTO ZERO key from unauthorized use.
51) Lock Aut Sp - Select YES to protect the AUTO SPAN key from unauthorized use.
52) Lock Stp Ct - Select YES to protect the STOP COUNT key from unauthorized use.
