Connecting the SmartLogger
Connecting the SmartLogger
Context
The PID module connects to the SmartLogger
over the RS485 communications terminals (JX01) in the smart array
controller. The RS485 communications ports on the PID module are from
an RS485 terminal block. Table 3-2 defines
the functions of the RS485 terminal block.

Connect the RS485 communications cable
to any A+ and B– ports of the RS485 communications ports on the PID
module, and connect the shield layer to the RS485 shield ground point.
This section uses the smart array controller with two PID modules
as an example to describe how to connect the PID module to the SmartLogger.
For the smart array controller with one PID module, refer to the way
of connecting one route of cable connection.
Procedure
Connect the RS485 communications cable
to the RS485 communications port on the PID module. The RS485 communications
cable is a two-core balanced twisted pair (brown and black) with a
cross-sectional area of 22 AWG (0.3 mm2).

Connect the other end of the cable to
the JX01 terminal block.
Connect the RS485 communications cable
to the COM1 port on the SmartLogger over the JX01 terminal block.
