Siemens Apogee P1 Communications Interface
SIEMENS APOGEE TECHNOLOGY OPTION
A System Overview
The Apogee P1 Technology Option provides a serial data port, allowing VSDs (variable speed
drives) to be linked to form a network. Using a PLC/SCADA or other intelligent device, this
network can be continuously controlled to provide supervision and monitoring for each VSD in
the system.
With each unit under local
control, the central
supervisor performs only
periodic setpoint updating,
control sequencing and data
collection.
In the system, the
PLC/SCADA supervisor
acts as the Master, and the
VSD as the Slave.
The network of VSDs can
be set-up using each unit’s
MMI/Operator Station.
Protocol
This card communicates using the Siemens Apogee P1 protocol. Any connections made to it
most comply with this protocol. Every effort has been made to maintain compatibility with
devices using this protocol.
Product Features
•Suitable for use with:
HVAC10 Drive Products software version 4.6 onwards
•Connection using 2 or 4-wire shielded twisted pair (RS485)
•Configured using Function Block inputs
•Protocol tag access for defined P1 parameters
Size Notation – Part Numbers
Size 1 HVAC10 drives use the 6053/APOG Apogee Technology Box.
All Size 2 and 3 HVAC10 drives use the 6055/APOG Apogee Technology Box.
Advantages with this type of control system
1. Multi-wire analog transmission from a central programmable
controller is replaced by a bussed digital system using serial
data transmission over differential twisted-pair wires.
2. Digital transmission is fundamentally less noise-prone than
analog methods, and the accuracy of the transmitted data is
unaffected by the transmission medium. The use of intelligent
devices at either end of the data link allows error checking to
be used. This virtually eliminates the effects of electrical noise
on data integrity. It is therefore possible to issue setpoints to
drives with much higher accuracy using this method.
3. The communication standard used allows up to 32 drives to be
connected to a single link which can be driven from a
computer serial port.
4. The chosen standard and protocol are compatible with other
Eurotherm Group products. Temperature controls, process
controls, data loggers and drives can communicate easily with
a common supervisory system.
