The Z-COM module joins with functional modules (Z-TIO, Z-DIO modules) and performs PLC
communication and host communication. The combination of Z-COM module and functional module
is called an SRZ unit.

WARNING
Indication lamp (RX1/TX1)
Do not mount this instrument directly above equipment that generates large amount of heat
(heaters, transformers, semi-conductor functional devices, large-wattage resistors).
If the ambient temperature rises above 50 °C, cool this instrument with a forced air fan, cooler, or
the like. However, do not allow cooled air to blow this instrument directly.
In order to improve safety and the immunity to withstand noise, mount this instrument as far
away as possible from high voltage equipment, power lines, and rotating machinery.

3.1 Wiring Cautions
ꢃ This instrument is protected from electric shock by reinforced insulation. Provide reinforced
insulation between the wire for the input signal and the wires for instrument power supply, source
of power and loads.
•
To avoid noise induction, keep communication signal wire away from instrument power line, load
lines and power lines of other electric equipment.
2.2 Joining Each Module
Communication port (modular connector) and Communication connector
•
If there is electrical noise in the vicinity of the instrument that could affect operation, use a noise filter.
ꢃ Be sure to provide an appropriate surge control circuit respectively for the following:
Before joining the Z-COM module and functional modules, use the DIP
switches to make the communication settings. For the setting procedure, see
Z-COM PLC Communication Quick Instruction Manual (IMS01T14-Eꢁ).
COM. PORT1
(Communication 1)
Used to connecting the Operation panel or Host computer.
[RS-485 or RS-422A]
−
Shorten the distance between the twisted power supply wire pitches to achieve the most
effective noise reduction.
−
If input/output or signal lines within the building are longer than 30 meters.
If input/output or signal lines leave the building, regardless the length.
−
−
Always install the noise filter on a grounded panel. Minimize the wiring distance between the
noise filter output and the instrument power supply terminals to achieve the most effective
noise reduction.
COM. PORT2
(Communication 1)
The COM. PORT2 is used for the extension of the SRZ unit.
[RS-485 or RS-422A]
ꢃ This instrument is designed for installation in an enclosed instrumentation panel. All high-voltage
connections such as power supply terminals must be enclosed in the instrumentation panel to
avoid electric shock by operating personnel.
The maximum number of functional modules (Z-TIO-A/B, Z-DIO) described in the following can be
joined per Z-COM module. For details on joining functional modules with the Z-COM module, see
the Z-TIO INSTRUCTION MANUAL (IMS01T01-Eꢄ).
COM. PORT3
(Communication 2)
Used to connecting the programmable controller (PLC), Operation
panel or Host computer. [RS-485 or RS-422A]
−
Do not connect fuses or switches to the noise filter output wiring as this will reduce the
effectiveness of the noise filter.
ꢃ All precautions described in this manual should be taken to avoid damage to the instrument or
