ECODRIVE03-FL*-04VRS Writing the User Program
6-3
DOK-ECODR3-FL*-04VRS**-FK01-EN-P
6.2 General Information
The basic programming is pre-set, and the user has no external access to
it.
The programming language for the user program is a code similar to the
BASIC programming language and was developed especially for use with
this program.
The user program can have a maximum size of 1000 instructions or lines.
Only one command is stored within each program instruction.
In programming, any four-digit program number between 0000 and 0999
is allowed.
The user program can be loaded via the serial port.
Program input can take place in any operating mode. A running program
should not be interrupted.
With most commands, the processing time for an instruction is exactly the
same as the CPU cycle time of 2 ms. After that, the instruction with the
next higher sequence number is processed (unless a jump instruction is
given). In the descriptions that follow, this action is called ‘proceed
immediately to next instruction.’
In the case of commands involving wait states for receipt of an outcome,
the process time is always extended by the cycle time required for the
outcome to arrive.
In most commands, both constants and variables can be used. For
clearer understanding, command examples are shown with variables and
with constants. If both example lines contain a variable or a constant in
the same location, only this type of value is allowed.
6.3 Program Input
The program can be loaded via the serial port of any computer having an
RS232C or RS485 interface.
Parameters B001 and B002 control the activation and setting of the serial
port. The programming module can be used to provide a default setting to
ensure establishment of a reliable communications link.
Handling of the interface and the transmission format used are described
in Section 10.2.
