4. COMMUNICATION SETTING
Set communication setting before mounting and wiring of SRV.
Do not separate the module mainframe from the terminal
base with the power turned on. If separated, adjusted data
may be destroyed; control be stopped, and no return can be
made.
4.1 Module Address Setting
Set an address of module. For this setting, use a small blade
screwdriver.

• For Modbus, the value obtained by adding “1” to the
set address corresponds to the address used for the
actual program.
• To avoid problems or malfunction, do not duplicate
an address on the same communication line.
The above figure shows when provided with the event
input/output connector, but the same also when not
provided with the connector.
4.2 Protocol Selections and
Communication Speed Setting
Use the DIP switch on the right side of module to select
communication speed, data bit configuration and protocol. The
data changes become valid when the power is turned on again
or when changed to RUN/STOP.

• Switch No. 7 and 8 must be always OFF. Do not set to
ON.
• When two or more modules are connected on the
same communication line, the DIP switch settings
(switch 1 to 6) of all modules must be the same.
• Be changed into communication time setting mode*
by using switch No. 4, 5 and 6.
For communication time setting mode, see the
Module Type Controller SRV Communication
Instruction Manual (IMS01P01-E ).
5. MOUNTING
5.1 Mounting Cautions
(1) This instrument is intended to be used under the following
environmental conditions. (IEC61010-1)
[OVERVOLTAGE CATEGORY II, POLLUTION DEGREE 2]
(2) Use this instrument within the following environment conditions.
• Allowable ambient temperature: −10 to +50 °C
• Allowable ambient humidity:
5 to 95 % RH
(Absolute humidity: MAX. W. C 29.3 g/m
3
dry air at 101.3 kPa)
• Installation environment conditions: Indoor use
Altitude up to 2000 m
(3) Avoid the following when selecting the mounting location:
• Rapid changes in ambient temperature, which may cause
condensation.
• Corrosive or inflammable gases.
• Direct vibration or shock to the mainframe.
• Water, oil, chemicals, vapor or steam splashes.
• Excessive dust, salt or iron particles.
• Excessive induction noise, static electricity, magnetic fields or
noise.
• Direct air flow from an air conditioner.
• Exposure to direct sunlight.
• Excessive heat accumulation.
(4) Mounting consideration
• Install the module 200 mm away from the main power line.
• Ensure at least 50 mm space on top and bottom of the control
unit for maintenance and environmental reasons.
