● Support of configuration of elements connected to UDFs (User-Defined Functions)
LOGO!Soft Comfort V7.0 provides a new circuit program editor - the UDF editor. Circuit
programs created in the UDF editor can be saved as individual UDF blocks for use in an
existing or a new circuit program in LOGO!Soft Comfort. A UDF block is a preconfigured
circuit program that you create. If the circuit program in your LOGO! 0BA7 contains a
UDF block, you can edit the elements connected to this UDF block.
● Support of data logging
You can configure the Data Log function only from LOGO!Soft Comfort V7.0. The Data
Log is used to record actual values of digital and analog I/O, digital and analog flags, and
function blocks. If the circuit program in the LOGO! 0BA7 contains the Data Log block,
you can configure the elements connected to it from the LOGO! 0BA7. You can select to
store the data log either in the LOGO! 0BA7 or on an SD card. You can also save the
data log to a .CSV file on your PC and open it with Microsoft Excel or with a text editor.
● Extended real-time clock backup time
LOGO! 0BA7 has a built-in real-time clock that supports a typical backup time of 20 days.
● More connectors and memory space for the creation of the circuit program
Four new connectors that represent network digital inputs/outputs and network analog
inputs/outputs are available in a LOGO! 0BA7 if you have previously configured them
from LOGO!Soft Comfort V7.0. In addition, you can now have up to 16 analog flags, 64
open connectors, 32 shift register bits, and a maximum program memory of 8400 bytes
for up to 400 function blocks in you circuit program.
● New special function blocks
Five new special function blocks are available: Astronomical Clock, Stopwatch, Analog
Filter, Max/Min, and Average Value.
New features of the LOGO! 0BA6 device series
The following features were new for the LOGO! 0BA6 devices:
● A new expansion module named LOGO! AM2 RTD is commercially available. The
module is equipped with two analog inputs for connection to PT100 and/or PT1000
sensors with the default temperature coefficient of α = 0.003850 for both sensor types.
The LOGO! AM2 PT100 expansion module, however, only supports PT100 sensors.
● The LOGO! AM2 RTD module can automatically recognize the sensor type. It is thus
unnecessary for you to make any configuration or setting to achieve this.
● Two new LOGO! versions LOGO! 24C and LOGO! 24Co (each with a built-in real-time
clock) are commercially available.
● The LOGO! TD (Text Display) provides an additional display device for messages, and
contains four cursor keys and four functions keys that can be used in the circuit program.
● An additional password protection function is available in the LOGO! TD (version ES4 or
later) and can only be enabled when the LOGO! TD is used together with a LOGO! Base
Module (version ES4 or later).
● The new LOGO! Battery Card and the LOGO! Combined Memory/Battery Card provide
up to two years of backup time for the real–time clock. The new LOGO! Memory Card and
the Combined Memory/Battery Card provide 32 Kbytes memory space.
