Overview
This manual describes the specifications, handling and programming meth-
ods for the PROFIBUS DP Master Module ME1PB1-L which is used with the pro-
grammable controllers of the MELSEC-L series.
The ME1PB1-L operates as a DP-Master (Class 1) on PROFIBUS DP networks and
is used for connecting MELSEC-L series programmable controllers to
PROFIBUS DP.

b: LED ON, v: LED flashing, : LED OFF
The LED flashes at intervals based on the value set in the Master Parameters.
The LED flashes at the time of request or response in acyclic communication.
The LED status during token passing varies depending on the number of DP-Mas-
ters within the same network and the transmission speed setting.
1 Master: TKN LED is ON regardless of the transmission speed.
More than 1 Master:
– Transmission speed 19.2 kbps or less: The TKN LED is flashing.
– Transmission speed 93.75 kbps or more: The TKN LED is ON or OFF.
Installation and Wiring
m
DANGER
● Turn off all phases of the power supply for the PLC and other external
sources before starting the installation or wiring work.
b
CAUTION
● Use the product in the environment that meets the "GENERAL SPECIFI-
CATIONS" in the manual "Safety Guidelines" included in the CPU mod-
ule or head module. Failure to do so may result in electric shock, fire,
malfunction, or damage to or deterioration of the product.
● Prevent foreign matter such as dust or wire chips from entering the
module. Such foreign matter can cause a fire, failure, or malfunction.
● Before handling modules, touch a grounded metal object to discharge
the static electricity from the human body. Not doing so may cause
failure or malfunctions of the module.
Mounting
b
CAUTION
● Modules must be mounted on a DIN rail.
● Connect an END cover on the last module on the right side.
● Do not drop the module or subject it to heavy impact.
● Do not open or modify a module. Doing so can cause a failure, mal-
function, injury or fire.
● Do not directly touch any conductive parts and electronic components
of the module.
● To interconnect modules, engage the respective connectors and
securely lock the module joint levers. Incorrect interconnection may
cause malfunction, failure, or drop of the module.
Connecting the modules
The procedure for connecting modules is shown with an example of how to
connect the L02CPU to the power supply module L61P.
To release the module joint
levers located at the top and
Release
bottom of the L02CPU:
Slide the levers toward the
front side of the module.
Insert the connector of the
CPU module into that of the
power supply so that they
are securely engaged.
To lock the module joint
Lock
levers:
Slide the levers toward the
back side of the module.
Make sure that the modules
are securely connected.
Mounting the Modules on a DIN rail
Pull down DIN rail hooks on
the back of the modules until
they click.
Hang the upper tabs of the
modules on a DIN rail, and
push the modules in posi-
tion.
Lock the DIN rail hooks to
the DIN rail to secure the
modules in the position.
Pull the hooks up until they
click. If the hooks are beyond
the reach, use a tool such as
a driver.
Mount stoppers on the DIN rail beside the leftmost and rightmost module,
to avoid lateral sliding.
NOTE
Do not slide modules from the edge of the DIN rail when mounting. Doing so
may damage the metal part located on the back of the module.
Wiring
b
CAUTION
● Do not lay PROFIBUS cables close to the main circuit, high-voltage
power lines, or load lines.
Otherwise effects of noise or surge induction are likely to take place.
Keep a safe distance of more than 100 mm from the above when
wiring.
● When disconnecting the PROFIBUS cable, do not pull it by holding the
cable part.
Be sure to hold its connector which is plugged into the module. Pulling
the cable with it connected to the module may damage the module
and/or cable, or cause malfunctions due to poor contact of the cable.
Applicable Cable and Connector
To connect the ME1PB1-L to a PROFIBUS/DP network, use only the PROFIBUS
connector and shielded twisted pair PROFIBUS cable complying with
EN50170.
Wiring precautions
Keep the PROFIBUS cable away from I/O module cables as much as possible.
