(2) MELSECNET/H module
Always use a double-shielded coaxial cable (MITSUBISHI CABLE INDUSTRIES,
LTD.: 5C-2V-CCY) for the coaxial cables MELSECNET/H module. Radiated noise in
the range of 30HMz or higher can be suppressed by using double-shielded coaxial
cables. Ground the double-shielded coaxial cable by connecting its outer shield to the
ground.
Refer to (1) for the grounding of the shield.
(3) Ethernet module, FL-net module, Web server module, MES interface
module
Precautions for using AUI cables, twisted pair cables and coaxial cables are
described below.
• Always ground the AUI cables
*1
connected to the 10BASE5 connectors. Because
the AUI cable is of the shielded type, strip part of the outer cover and ground the
exposed shield section to the ground on the widest contact surface as shown in
Diagram 9.5.
Refer to (1) for the grounding of the shield.
* 1: Make sure to install a ferrite core for the cable.
As a ferrite core, ZCAT2032 manufactured by TDK is recommended.
• Use shielded twisted pair cables as the twisted pair cables connected to the
10BASE-T/100BASE-TX connectors. For the shielded twisted pair cables, strip
part of the outer cover and ground the exposed shield section to the ground on
the widest contact surface as shown in Diagram 9.6.
Refer to (1) for the grounding of the shield.
• Always use double-shielded coaxial cables as the coaxial cables
*2
connected to
the 10BASE2 connectors. Ground the double-shielded coaxial cable by
connecting its outer shield to the ground.
Refer to (1) for the grounding of the shield.
* 2: Make sure to install a ferrite core for the cable.
As a ferrite core, ZCAT3035 manufactured by TDK is recommended.
