INSYS GSM 4.2 easy, Add-On Manual

Page: 9 / 39

The controller requires additional memory for the functions to generate
pulses. Compact controllers in particular have a rather limited memory for
control programs.
Due to additional functions which have no effect on the actual system
function, the control program will be more complex and confusing.
Programming pulse creation requires effort and time.
Valuable outputs of the compact controllers are used, because they are
needed for the pulse output.
2.3 Restrictions / Notes
Since the INSYS GSM 4.2 easy is connected to the Moeller easy device via a
serial interface, a memory can not be used simultaneously with the INSYS
GSM 4.2 easy.
The password protection of the easy device may not be activated. If it is ac-
tivated, no communication between INSYS GSM 4.2 easy and the compact
controller is possible. However, the INSYS GSM 4.2 easy has its own pass-
word protection, which prevents unauthorized persons without knowledge
of the exact password from remotely accessing the compact controller.
The LCD display needs to be in its original state before the Moeller easy
controllers can communicate via their RS232 interface. This means, for ex-
ample, that if the controller is put into another condition by hitting keys on
the device, or if the control program is manually modified, the user has to
leave all sub menus of the easy device. This is necessary that the INSYS
GSM 4.2 easy can communicate with the easy device.
As it is possible to intervene in registers of the current easy control pro-
gram with the help of SMS commands via the INSYS GSM 4.2 easy we again
refer to the documentation of the used Moeller easy 800 or easy MFD de-
vices. In the easy device, the storage location for registers can be used
twice; the instances of the registers should therefore be chosen with care
to prevent the registers from manipulating each other.
Recommendation:
Object Instance from
Bit register M 1
Byte register MB 13
Word register MW 49
Double word register MD 49
