2.4 - The WATCH and POSITION windows

The position window is accessed through the “Position” command of the View pull-down menu, ALT+V and P from the

terminal window. It is a very convenient way to continuously check PMAC parameters such as position velocity and

following error. Right-clicking on this window allows the items selections as well as its format and update period.

The “Watch” window of the same View menu performs a very similar function. Instead of the motion-related parameters

allows to constantly display any variable value in PMAC. Right-clicking on this window allows selecting the display format

from hexadecimal, decimal and binary reporting values.

2.5 - Uploading and Downloading files

These functions are accessible through the “File” pull-down menu. The uploading function is of great importance. Through

it is possible to open a text editor with the contents of the requested PLC, Motion Program, M-variables definitions or

values, I variables values and so on. This allows not only to check what commands or values PMAC has actually in

memory but also will indent IF conditions and WHILE loops, making the program flow better readable. The File pull-down

menu also activates a more interactive and complete editor utility, providing a way (also by the communication functions) to

compile PLCs and download files including MACRO names.

2.6 - Using MACRO names and Include Files

PEWIN allows using names meaningful for the user in replacement of the common names for variables and functions that

PMAC expects (P, Q, M, I):

Example:

Make sure the “Support MACRO’s/PLCCs” option is checked before downloading. The MACRO must be defined before it

could be used. In general, MACRO definitions are at the beginning of the text file. MACROs must be up to 255 valid

ASCII characters and cannot have spaces in between (the underscore “_” is suggested in place of a space).

The MACRO definitions, or any PMAC code, could be placed in a separate file and be included with a single line in the text

file. The file name must be complete of a full path in order for PEWIN to find it.

Example: #include "c:\deltatau\files\any.pmc"

2.7 - Downloading compiled PLCCs

PLCCs are compiled by PEWIN in the downloading process. Only the compiled code gets downloaded to PMAC.

Therefore, it is suggested to save the ASCII source code in the host computer separately since it cannot be retrieved from

PMAC. Compiled PLCs are firmware dependent and so they must be recompiled when the firmware is changed in PMAC.

If more than one PLCC is programmed, all the PLCCs code must belong to the same ASCII text file. PEWIN will compile

all the PLCC code present on the file and place it in the appropriate buffer in PMAC. If a single PLCC code is downloaded,

all the rest PLCCs that might have been present in memory will be erased, remaining only the last compiled code.

The multiple-file download feature of the PEWIN File menu allows having the PLCC codes in different files. They will be

combined by PEWIN in the downloading process.
