The FlowGo Interface
DO96 (4)
Using FlowGo away from the computer
There are two distinct modes of operating FlowGo.
1. It can be used connected to the computer and operated as an ordinary real-
time control interface with the
Go
application performing the processing of a
program.
2. It can run a program that has been created in
Go
whilst away (disconnected)
from the computer. The
Go
program is stored and processed by a
microprocessor in FlowGo.
The program is stored in non-volatile memory so even if the power is
disconnected or turned off; the program will
not
be lost. When the power has
been reconnected, press the GO button on FlowGo and the stored program will
run.
The microprocessor in FlowGo can be reprogrammed repeatedly.
Stored program limits
There is a 256 bytes memory limit to the size of the program that can be downloaded
to FlowGo. The size of a program entirely depends on its complexity. For the
simplest program (one start, switching single outputs on or off with the same wait
value) FlowGo will accept a maximum of about 170 symbols.
Note:
When you ‘test compile’ or ‘compile and download’ your program the memory used
indicator will show an approximation of the amount of memory used (see page 16).
There are also some program limits to a program for download and if they are
exceeded an error message will be displayed.
•
Use a maximum of 4 flowcharts (Starts)
•
Use only Variables x and y
•
Use a maximum of 16 different valued Wait commands (If ‘Wait 2 seconds’ is
used 5 times in a program then this will be counted as one value of wait. If ‘Wait
1’, ‘Wait 2’ and ‘Wait 3’ are used this will count as three values of wait)
•
Use a maximum of 16 different constants
•
Use a maximum of 16 different Procedures (If ‘Procedure: Flash’ is used 3 times
in a program then this will be counted as one procedure. If three different
procedures are used they will count as three procedures)
•
Motor speed control variables are not suitable
•
Sound commands are incompatible
•
Binary input commands are incompatible. Binary output commands can be used
but will not reduce program size.
