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 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 recommended 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 illuminate continuously 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 50155 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

1. Use 18 AWG wire for the power ground.

2. Grounding the device through the earth/ground pin ( ↓ ) gives 6kV ESD protection.

Installing a microSD Card

The ioPAC is equipped with one slot for a microSD card. 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 card. 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.

1. (a) Insert the microSD card into the microSD card slot, or (b) Remove the microSD card from the microSD card slot.

1. 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:

RJ45 Connector Pin Assignment

Contact Media Direct Interface Signal
1 Tx +	(transmit)
2 Tx -	(transmit)
3 Rx +	(receive)
4 Not used
5 Not used
6 Rx -	(receive)
7	Not used
8 Not used

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.

The following diagram and table shows the pin connections for the M12 Ethernet connector:

M12 Ethernet Connector Pin Assignments

Male	Wire-Color Bus	Reference

2	Not used n.c -
3	- Shield S
4	Blue -1	A

In what follows, we give pinouts for both MDI (NIC-type) ports and MDI-X (HUB/Switch-type) ports. We also give cable wiring diagrams for straight-through and cross-over Ethernet cables.

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.

System LEDs

PWR (Power LED)

The Power (PWR) LED indicates the status of the system power. When the system is on, this LED will turn green, and when the system power is off this LED will be off.

RDY (Ready LED)

The Ready (RDY) LED indicates the status of the system's kernel. When the LED is green the system kernel is ready. When the LED is green and blinking, the system's kernel is booting-up. When the Ready (RDY) LED is red, there is either a system error or the system is being reset to factory defaults. When the Ready LED is red and blinking, the device's factory default mode has been triggered.

IO (Expansion Module LED)

The IO LED on the module indicates the status of the expansion modules. When the LED is green, all expansion module configurations are okay, and when the LED is red, at least one of the expansion modules failed to configure properly.

C/C++ Version LEDs: LED1 and LED2

The ioPAC controller allows the user to custom configure these two LEDs (through the software interface). Refer to the C/C++ Sample Code Programming Guide for ioPAC RTU Controllers for details.

IEC-61131-3 Compliant LEDs: R/S and ERR

The ioPAC controller supports IEC-61131-3-compliant Run/Stop and Error (ERR) LEDs for ISaGRAF-specific notifications. These LEDs are not user configurable.

Communication LEDs

P1 and P2

The ioPAC controller comes with two serial connections. P1 and P2 represent the status of each serial connection. When the LED is green, the ioPAC is transmitting data (Tx). When the LED is amber, the ioPAC is receiving data (Rx). When the LED is blinking randomly, data is either being transmitted or received. For example, if P1 is blinking and is green, the ioPAC is transmitting data.

When the LED is off, the serial connection is disconnected.

LAN1 and LAN2

The ioPAC controller comes with two Ethernet ports, with the LAN1 and LAN2 LEDs used to represent the status of the two connections. When the LED is green, data is transmitting at 100 Mbps. When the LED is amber, data is transmitting at 10 Mbps. When the LED is blinking, data is being transmitted. When the LED is off, there is no Ethernet connection, or the Ethernet connection has been disconnected.

The Toggle Switch

The toggle switch functions differently depending on the programming language set your ioPAC model is configured for.

In IEC-61131-3 Models

For IEC-61131-3 models, the toggle switch is a simple run/stop switch for IEC programs. Users can enable or disable it through RTUxpress. The default setting is disabled.

In C/C++ Models

On models that use the C language set, the toggle switch is programmable, giving integrators and end-users a switch that can trigger one of two operation modes (refer to the C/C++ Sample Code Programming Guide for ioPAC RTU Controllers for details).

Toggle Switch: Factory Reset Process

Use the following procedure to reset the ioPAC to the factory defaults. Note that when you reset the ioPAC, all of your tag definitions, software programs, and files will be deleted, and the service and runtime engine will be restarted.

1. When the system is booting up and the RDY LED is blinking GREEN, hold the toggle switch in the "reset" position.
2. Continue to hold toggle switch until the "RDY" LED turns a solid RED, and then release the toggle switch. It will take around 90 seconds to complete the factory reset process.
3. When the "RDY" LED starts blinking GREEN (indicating that the kernel is rebooting), the factory mode is completed.

NOTE Do NOT power off, operate, or connect any devices when the RDY LED is a solid red. The factory reset function is only activated when the system is booting up.

Pin Assignment and Wiring Guide

The following is the 85M-38XX-T module's pin assignment and wiring guide.

Analog Input Data Format

The I/O analog inputs have a 16-bit, unipolar, and analog to digital (A/D) converter that measures input voltages from 0–10 V and current from 4–20 mA (with Burnout). The following chart is the raw data conversion table for current and voltage.

The voltage ranges from 0 to 10 V. The lowest voltage of 0 V represents raw data of 0, and the highest voltage of 10 V represents raw data of 65535. When the raw voltage data is at 1, it represents 0.15 mV. The current ranges from 0 to 20 mA. The lowest current of 0 mA represents a raw data value of 0. Users can manually adjust the burnout value from 0 to 4 mA. All raw data below the burnout value will be 0. The highest current of 20 mA represents raw data of 65535. Raw current data of 1 represents 0.3125 μA.

Burnout mode can indicate if the current analog input has burned out.

NOTE Please refer to the ioPAC RTU Software User's Manual for the burnout mode settings.

NOTE

Grounding the device through the earth/ground pin (↓) gives 6kV ESD protection.

The 4–20 mA burnout mode values are defined in the following diagram:

Users can define burnout values for selected ranges. When input values are in the burnout range, raw data will register as 0000h to indicate analog input burnout. The definition of raw data is as follows:

Burnout Value (BO)	0.0 < BO < 4.0	User-defined (default: 2 mA)
Burnout State	0 ≤ AI < BO mA	S/W output 0000h
Under Range	BO ≤ AI < 4 mA	S/W output raw data
Normal Range	4 ≤AI ≤ 20.00 mA	S/W output raw data until FFFEh
Over Range	XX > 20.00 mA	S/W output FFFFh
