Basic module (head station) of the
MELSEC ST series
The basic module ST1H-PB connec ts the
remote I/O modules of the ST series to
PROFIBUS/DP.
The ST1H-PB provides a Mini-DIN socket
for diagnostics and parameter setting.
The station number can be set via DIP
switches on the basic module. LEDs
show the status ofthe connected systems.
Bus power for head station
The Bus power supply and refresh mod-
ule ST1PSD can serve in two ways: dis-
tribute 24 V DC power supply for the
basic module and I/O devices plus
5 V DC for the internal backplane bus
(H mode) or distribute 24 V DC power
supply for I/O devices and refresh the
internal backplane b us with 5 V DC
(R mode). Each mode (H or R) is indi-
cated by the use of a different base mod-
ule, marked with "H" or "R".
You need 1 ST1PSD with H -type base
module beside the basic module to
operate the ST station, a second or more
(usingtheR-typebasemodule)areonly
needed depending on the power con-
sumption of the c onnec ted items ( see
bottom of this p age).
LEDs on the module show the s tatus for
RUN and ERROR. Diagnosis can be made
via the head module.
Power feeding module
The power feeding module ST1PDD dis-
tributes 24V DC only for the I/Os of the
actuators and sensors.
The number of ST1PDD modules needed
can b e calculated individually b y addi-
tion of the current consumption of all
connected devices.
The electronic module is fitted in a base
module, which can be installe d on a
standard DIN rail.
