Siemens APOGEE P1 Communications Interface
The APOGEE P1 Technology Option provides a serial data port, allowing VSDs (variable speed
drives) to be linked to form a network. Using an APOGEE Controller, 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 APOGEE
controller 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.
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.
• Suitable for use with:
HVAC10 Drive Products software version 4.6 onwards
• Connection using 2 wire shielded twisted pair (RS485)
• Configured using Function Block inputs
• Protocol tag access for defined P1 parameters
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. Temperature controls, process controls, data loggers and
drives can communicate easily with a common supervisory
system.
