5 Functions of the GLT x010 and set-up
5.1 Implementation
The freely programmable controller is shipped from the factory without application functions. There is no
application loaded. All relay outputs are switched off. In contrast, the inputs are constantly read in even when
the application is missing or stopped. The values can be visualised with LDSWin.
If the application is missing or stopped, the life lamp (life LED) on the lower circuit board lights intermittently
(periodically on for approx. 3 s and off for 0.3 s).
Only the firmware that has the following functions is installed at the factory:
1. Install firmware - with and without applications
A function that allows installing a new firmware via the serial interface RS232. There are two versions of the
software installed on delivery:
a. Firmware without application
b. Firmware with application
2. Provision of the interfaces for CODESYS
a. RS232 - only for the CODESYS programming system
b. RS485 - only for Modbus RTU
c. CAN bus - only for the E*LDS system
d. EEPROM - for the non-volatile saving of setpoints
e. real-time clock
3. Cycle control and management of the process image (PI)
The procedure for installing a new firmware with or without applications is identical to that of a firmware
update.

The following must be ensured when starting up:
The desired CODESYS application has been loaded into the controller.
All manual control switches have been set to a position that is appropriate for the process, see
chapter Manual / Automatic operating modes changeover.
