5.2. Installation and starting the operator program
5.2.1. PC requirements
The HMI for the RE. 316*4 runs in the protected mode. The
minimum requirements for the PC are 16 MB of RAM, 12 MB free
hard disc space and an operating system MS Windows 3.x,
Windows 95 or Windows NT4.0 or higher. A 486 series proces-
sor or higher is recommended.
The HMI communicates with the RE. 316*4 at a baud rate of
9600 Baud. A problem can be encountered with some PC’s if the
memory manager EMM386 is active.
Temporarily disable the EMM386 memory manager by entering
‘REM’ at the beginning of the corresponding line in the ‘con-
fig.sys’ file:
REM DEVICE=..........\EMM386........
Disabling the EMM386 memory manager is recommended. The
consequence is less PC main memory below 640 kB, because
the device drivers are loaded there instead of in the upper mem-
ory range. This, however, has no influence on the operation of
the HMI.
5.2.2. Installing the operator program
We recommend the strict observation of the following points be-
fore installing the software on a your hard disc:
1. Ensure that your original floppy discs are write-protected.
2. Make backup copies of the original discs. Store the original
program discs in a safe place and use the copies to install the
program.
The program is located on the floppy discs labelled “RE.316*4
Software” in compressed form. There is also an installation pro-
gram on the disc to simplify the installation program.
Installation on a hard disc under Windows 3.1 / 3.11:
1. Insert the first disc “Disk 1/4” into drive A.
2. Select ‘Run’ in the ‘File’ menu and enter ‘a:\setup’ in the win-
dow that opens.
