ELAU PacDrive C600 Controller Integration Guide

EtherNet/IP: Optional hardware module is required, supporting either Scanner or Adapter modes.

2. PacNet high-speed I/O bus (X12, X13)

PacNet is ELAU's proprietary high-speed expansion bus used to connect distributed I/O modules. Through PacNet, up to 128 digital inputs, 128 digital outputs, and 128 Touchprobe inputs can be expanded. This is crucial for applications that require a large amount of high-speed signal acquisition.

3. Ethernet (X10)

Provide standard 10/100 Base-T Ethernet interface (RJ45). Based on the TCP/IP protocol stack, it supports the following functions:

OPC Server: Provides OPC DA interface that seamlessly integrates with SCADA or HMI software on any Windows platform (such as Intellution iFix, Siemens WinCC).

Web server: allows remote monitoring of controller status, variables, and diagnostic information through a standard browser.

FTP server: facilitates remote uploading/downloading of program files, recipe data, and logs.

SMTP: Supports sending alerts and event notifications via email.

4. Serial interface

COM1 (X17): RS232， It can be used to connect serial HMI panels, barcode scanners or Modbus RTU devices.

COM2 (X18): RS485， Support multi station Modbus RTU communication or connection to smart meters.

5. Main encoder interface (X11)

This interface is used to connect an external spindle encoder and achieve tracking of the spindle's motion. Supports two types:

SinCos absolute value encoder: 1 Vpp sine/cosine signal, with reference signal and RS485 parameter channel (for reading absolute position).

Incremental encoder: supports A, B, O (zero position) differential signals.

Important Warning: The manual clearly warns that the main encoder plug must be plugged in and out while the controller is powered off, otherwise it may cause hardware damage.

Onboard I/O: meets basic control requirements

For small applications or situations that do not require remote I/O, the C600 integrates a considerable number of native I/O points, reducing the cost and space of additional modules.

1. Digital input (X3)

Quantity: 20 points, compliant with IEC 61131-2 Type 1 specification.

Electrical characteristics: High level effective (DC 20-33V is logic "1", 0-6V is logic "0"), typical input current value is 5mA @ 24V.

Filtering: Parameterized selection of 1 ms or 5 ms input filtering to eliminate contact jitter.

2. Digital output (X2)

Quantity: 16:00.

Electrical characteristics: The output high level is (UL-3V) to UL (UL is the externally supplied logic voltage, connected to pin 3 of X1), the rated current is 250 mA/channel, and the surge current can reach 2 A for 1 second. The output has short-circuit protection.

Transmission delay: Typical value of 100 µ s, suitable for high-speed switch signals.

3. Interrupt input (X4)

Quantity: 4 points (shared some pins with Touchprobe input, but logically independent).

Function: Can be configured as an event triggered interrupt, used for signal processing with extremely strict time requirements (such as emergency stop, position capture trigger, etc.).

4. Touchprobe input (X4)

Quantity: 16:00 (T.00-T.15).

Resolution: 100 µ s; when the SERCOS cycle time is 1, 2, or 4 ms, the resolution can be increased to 10 µ s.

Typical application: When the rising edge of the photoelectric sensor is detected, the instruction position or actual position of the current axis is immediately locked for registration control, printing mark correction, etc.

5. Analog input (X5)

Quantity: 2 channels.

Range: Voltage mode: -10 V to+10 V; Current mode: -20 mA to+20 mA (to be selected through bridge connection J.0+or J.1+terminal).

Resolution: 12 bits (voltage 5 mV/LSB, current 5 µ A/LSB).

Input impedance: voltage 100 k Ω, current 500 Ω.

6. Analog output (X5)

Quantity: 2 channels.

Range: -10 V to+10 V.

Resolution: 12 bits (5 mV/LSB).

Load capacity: It is recommended to load>5 k Ω.

Auxiliary power supply: X5 also provides two 12V output voltages (12 V Out 0/1), which can be used to power external sensors.

7. Additional I/O Expansion

The maximum expandable digital/analog I/O capacity through PROFIBUS DP or PacNet bus is 3584 bytes each.

Requirements for power supply, environment, and mechanical installation

The design of C600 takes into account the actual conditions of industrial sites, but must comply with the following limitations to ensure long-term reliable operation.

1. Power specification (X1)

Main power supply: DC 24 V (-15%/+25%, i.e. 19.2 V to 30 V), maximum power consumption of the controller itself is 85 W (approximately 3.5 A).

External logic voltage (UL): provides driving power for digital output, also DC 24V, and needs to be separately connected to pin 3 of X1. This voltage is electrically isolated from the internal logic of the controller.

Watchdog Relay (WD): pins 7 and 8 of X1 are passive contact relay outputs. When the controller software is running normally and the watchdog is not triggered, the relay will close. If a serious malfunction or power outage occurs, the relay will release and can be used to drive external safety circuits.

UPS option: Internally available uninterruptible power supply (UPS), allowing for safe data storage and controlled shutdown in the event of an external 24V power outage. The maintenance cycle for UPS batteries is 3 years.
