CTC’s EtherCAT
Master with
Turck
I/O Blocks
This document discusses capabilities and setup information when using the CTC
EtherCAT Master with Turck I/O Blocks.
CTC’s EtherCAT master combined with Turck I/O blocks form an unbeatable combination for ease of use and cost/performance.
Auto-Configuration Simplifies Programming
Device Monitoring Using EtherCAT Explorer
When equipped with a model M3-41 EtherCAT Master module,
the CTC model 5300 controller will automatically recognize and
configure Turck I/O blocks that are connected via a Turck BL20E-GW-EC EtherCAT coupler. This eliminates what can be one
of the most time-consuming aspects of setting up an EtherCAT
network, greatly simplifying the process of system configuration.
Programming is then a simple matter. In the QuickBuilder programming environment, EtherCAT I/O devices appear identical
to local I/O, with the same commands used to control them.
Part of the QuickBuilder environment is a powerful diagnostic
and monitoring tool for EtherCAT networks – the EtherCAT
Explorer. For each EtherCAT master present in a controller, the
EtherCAT Explorer shows each of the EtherCAT nodes identified by that master, along with any drives or I/O points contained within that node.
Select one of the connected devices in EtherCAT Explorer to see
a detailed list of parameters associated with that I/O device. You
can also view a log of communications transactions sent across
the network. This provides a powerful network diagnostic capability and a detailed window into the functioning of the devices
in your system.
EtherCAT Explorer, in the QuickBuilder Programming Environment, provides a detailed view of the I/O on an EtherCAT network.
Powerful I/O Options
Programming in QuickBuilder
Used as Machine I/O - EtherCAT I/O is mapped as Controller I/O in QuickBuilder, as if it were plugged into the controller rack.
The CTC model 5300 controller is programmed with QuickBuilder, a comprehensive graphical programming environment. The advanced instructions are programmed using
Motion Sequence Blocks (MSBs, such as the one circled in
red in the illustration), which are automatically downloaded
to the appropriate EtherCAT Master module for local execution. This greatly increases performance while still allowing
intensive communication with the main controller program.
Example:
// Turn on output#1
O1_ClampPart = On;
// Check the end of travel limit
if I7_ExtendLimit == Made then goto Retract;
PLS Outputs (Programmable Limit Switch) - Set and Clear
Outputs based on axis positions.
Example:
//Output will turn on when axis feedback
position count is within 100000-250000 or
1750000-3000000
pls 1 using fposc on 100000 to 250000, on
1750000 to 3000000;
PWM Outputs (Pulse-Width-Modulated) - Send pulses with
timed states for On and Off.
Example:
//Set PWM on output#2 – 125 ms ON 1000 ms
OFF for 5000 cycles

Sequence Block named Slide.
pwm output 1002 on 125 off 1000 cycles 5000;
Pulse Outputs - Automatic generation of pulses
Example:
//turn out#2 (+1000=remote I/O) on for 500
ms
pulse_ext 1002 for 500;
Software (Pulse) Counters - Automatic counting of input
transitions
// Set the first counter to count pulses on
in#25 (+1000=remote I/O)
set mapped input 1 to input 1025 count
