12. Address Setting
Savch PLC with Ethernet port, the default IP address is: 192.168.1.111, subnet mask:
255.255.255.0, gateway: 192.168.1.1. Hardware DIP dial switch address range: 1-15,
the default address is 1. If you need to set a bigger address range, you can set on the
software after connection with PLC, it can be set on the PLC parameter option in the
software menu by checking on the "soft address" with the range of 1-254(the soft
address is prior to the hardware dial address).
13. Power Supply Wiring
There are two kinds of power supplies for PLC: AC input and DC input. Please pay particular attention to the
following notes:
•
AC input voltage is 100~240VAC 50/60Hz unless otherwise stated. Connecting any one of the AC input
wires to the terminal-L and terminal-N on the MPU will be OK, but for safety's sake, please connect the
two wires (Live Wire & Neutral Wire) of AC input to terminal-L and terminal-N respectively.
•
Any AC110V or AC220V connected to the +24V terminal or input points will permanently damage the
PLC.
Please use wires of 2.5mm or above for the grounding of the MPU.
14. Mounting and installation
The PLC should be secured to an enclosed cabinet
while mounting. For heat dissipation, make sure to
provide a minimum clearance of 50mm between
the unit and all sides of the cabinet. (See the
figure.)
Rail Mounting:
Use standard 35 mm rail.
Screw Mounting:
Each MPU or extension module
has two positioning screw holes, the diameter of
the hole is 4.5mm. Please refer to the dimension
figure for the location of the positioning holes and
their spacing.
To avoid over temperature and for a better heat
dissipation, do not mount PLC to a position near to
the bottom/top of the cabinet. Do not mount PLC in
vertical direction.
Extension Module Wiring:
Connections between
extension modules and connections between
module and MPU are achieved through bus. An
extension cable will be configured to every
extension module, for the connection between two
different modules.
Connection methods:
turn the right side of
extended interface (the last MPU or extension
module) over, plug the extension cable in the
extended interface, then press down the cover of
the extended interface to reset the interface, the
extended interface at the right side of the module
will be reserved for extension of the next module.
Connect all extension modules in turn in the same
way.
