3.6 About Dedicated Input/Output
Signal numbers are assigned to 2D
-
TZ577 Cards. Assignment of these numbers to dedicated input/output
parameters permits them to be used as dedicated input/output. For more information about the dedicated
input/output, see Section 6 "Functions of External Input/Output" of the "Instruction Manual
- Detailed Description
of Functions and Operation" which is separately issued.
3.7 Specification Relative to Robot Language
The follow subsection explains robot language (MELFA
-
BASIC V) which pertains to the 2D
-TZ577 Card.

To avoid "Data separation" a read/write interlock as shown below need be provided in the application concerned
(robot program or PLC ladder).
An example of interlock being used where one-word data is sent from the Master Station to the robot is
illustrated in the form of a flowchart below.
