Basic Installation

DIN Rail Installation Procedure

Installing the ioPAC 8500 on a DIN Rail

The DIN rail attachment plate should already be fixed to the back panel of the ioPAC 8500 when you take it out

of the box. If you need to reattach the DIN rail attachment plate to the ioPAC 8500, be sure the spring-loaded

bracket is situated towards the bottom, as shown in the figures below.

NOTE

A wall

mount kit can be purchased separately.

STEP 1:

If the spring-

loaded bracket is locked in place, push the

recessed button to release it. Once released, you should feel

some resistance from the spring as you slide the bracket up and

down a few millimeters in each direction.

STEP 2:

Insert the top of the DIN rail into the top

slots on the DIN rail attachment plate.

STEP 3:

The DIN rail attachment unit will snap into

place as shown in

the illustration below.

Removing the ioPAC 8500 from a DIN Rail

To remove the ioPAC 8500 from a DIN rail, use a screwdriver to push down

the spring-loaded bracket until it locks in place, as shown in the diagram at

the right. Next, rotate the bottom of the switch upwards and then remove the

switch from the DIN rail.

Module Installation Procedure (Power-Off)

Moxa’s ioPAC 8500 controllers come with 2, 5, or 9 slots for 85M-series modules. Use the following procedure

to install modules when your system is powered off.

Step1: Install the module into the ioPAC 8500 system. The module’s PCB should align with the edge of the

frame. Push the module into the slot and make sure the module is plugged into the backplane.

Step2: Fasten the two screws using 3.5±0.5 kg of torque.

Module Installation Procedure (Power-On)

All ioPAC 8500 modules are hot-swappable, which means that you can safely install, remove, and replace

modules while the system is powered on. When a module is removed or installed when the system is powered

on, the module head stops processing and registers the newly installed or recently removed module, and scans

for a configuration change. There is no disruption to normal operation during module insertion or removal.

After installing a new module, it could take about ten seconds for the system to recognize and activate the

module, at which point the module’s LED will turn green.

WARNING

When the system is

powered on

, do not install more than one module at a time. If you need to install multiple

modules, wait until the most

recently installed module’s LED turns GREEN before installing the next module.

Configuring the Power

Powering on the ioPAC Controller

The ioPAC controller can receive power from a 9 to 48 VDC power source, and is

compliant with EN 50155 at 24 VDC. Input power is applied to the positive (V+) and

negative (V

-) terminals on the connector.

•

When the input voltage is below the minimum recommen

ded voltage the ioPAC

will turn off.

•

The ioPAC has reverse protection and power input over-voltage protection,

allowing it to resist a maximum voltage of 60 V, and the ioPAC’s power input

over-current fuse protection specification is 5 A.

After connecting the Moxa ioPAC controller to the power supply, it will take 30 to 60 seconds for the operating

system to boot up. The green Ready LED will not turn on until the operating system is ready.

ATTENTION

This product is

intended to be supplied by a Listed Power Unit with output marked “LPS” and rated for 9-

48 VDC

(minimum requirements). For railway rolling stock applications, these devices must be supplied by a galvanic

isolated power supply with design based on the EN 5

0155 standard.

Grounding the ioPAC

For most applications, it is desirable to ground the system by connecting the system’s power supply common

wire to the chassis or panel ground. The negative (–V) side of the DC power input terminal as well as all I/O

point terminals labeled GND are connected to chassis ground.

NOTE

Use 18 AWG wire for the power ground.

We highly recommend connecting the ground screw to the power terminal block’s ground.

Installing a microSD Card

The ioPAC is equipped with one slot for microSD cards. The card reader slot is located inside the ioPAC device,

so you will need to unscrew and remove the card cover to install your microSD cards. When inserting a microSD

card, remember to keep the front edge of the card facing down.

Follow these steps to remove or install a microSD card:

1. Remove the screw holding the card cover in place.

2. (a) Insert the microSD card into the microSD card slot, or

(b) Remove the microSD card from the microSD card slot.

3. Fasten back the screw holding the card cover in place.

Connecting to the Network

Ethernet Communication

Connections to the LAN port are made through an RJ45 or M12 connector on the module. The wiring and pin

connections for these connectors are described in separate sections below.

• TCP/IP Settings: Dual Speed Functionality: The ioPAC 8500’s Ethernet ports auto negotiate with the

connected devices and then use the fastest data transmission rate supported by both devices. The following

table shows the TCP/IP parameters supported by the LAN port. Default values are set when a Factory Reset

is performed on the controller.

Lan Port 1 Lan Port 2

Parameter Supported Values Parameter Supported Values

IP Address Default: 192.168.127.254 IP Address Default: 192.168.126.254

Subnet Mask Default: 255.255.255.0 Subnet Mask Default: 255.255.255.0

Gateway Default: 0.0.0.0 Gateway Default: 0.0.0.0

IP Address is the IP address of the controller.

Subnet Mask determines the subnet on which the controller is located.

Gateway determines how your controller communicates with devices outside its subnet. Enter the IP

address of the gateway.

The IP address, subnet mask, and gateway are static; contact your network administrator to obtain these

addresses for the controller.

RJ45 Ethernet Connector

The ideal maximum cable length of a 10/100BaseT connection is 100 m (350 feet), but the actual limit could be

longer or shorter depending on the amount of electrical noise in the environment. To minimize the amount of

noise, Ethernet cables should not run parallel to power cables or other types of cables that generate electrical

noise.

The following diagram and table shows the pin connections for the RJ45 Ethernet connector.

M12 Ethernet Connector

The ioPAC 8500 has two 10/100BaseT(X) Ethernet ports that use 4-pin shielded M12 connectors with D coding.

The 10/100T(X) ports located on the front panel of ioPAC 8500 are used to connect to Ethernet-enabled devices.

Most users configure these ports for Auto MDI/MDI-X mode, in which case the port’s pinouts are adjusted

automatically depending on the type of Ethernet cable used (straight-through or cross-over), and the type of

device (NIC-type or HUB/Switch-type) connected to the port.

• The Auto MDI/MDI-X function (M12 connector) allows users to connect the ioPAC 8500’s 10/100BaseTX

ports to any kind of Ethernet device, without needing to pay attention to the type of Ethernet cable being

used for the connection. This means that you can use either a straight-through cable or cross-over cable to

connect the ioPAC 8500 to Ethernet devices.

ATTENTION

Configuring the two LAN ports on the same ioPAC RTU controller to the same network domain (e.g.,

192.168.1.1 and 192.168.1.2) is not recommended.

Port Trunking

The ioPAC 8500 RTU controller has a Port Trunking function (active backup mode) that can convert two

LAN-port IP addresses into one virtual IP address for easy SCADA integration and Ethernet redundancy. In the

following diagram, both LAN ports on each ioPAC RTU controller are connected to a managed switch on an

Ethernet network running SCADA software. For more details regarding configuration setup, refer to the ioPAC

RTU Software User’s Manual.

Serial Connectivity

Connecting to a Serial Device

The ioPAC RTU is equipped with two 3-in-1 serial ports that support RS-232/422/485, making it more

convenient to connect field serial devices.
