which will represent faults corresponding to these
numbers. Zeros are used to complete the 68-character
packet.
Monitor data will be sent by the DMR on request of the
press control. The two ASCII characters of the "Request
to Send Monitor Data" will be CC. The packet length of
the request will be two characters. The DMR will then
send the monitor data in a packet of bits representing
ASCII characters. The first two ASCII characters will be
CC. The remaining characters will contain the monitor
data. Zeros are used to complete the 68-character
packet. Numbers in the monitor data will be four digits
with an implied decimal point.
When ready, the press control will send a two-character
packet to the CES controller instructing the DMR to
execute the new parameters. The two ASCII, characters
in this packet of bits will be DD. All characters in the
packet will be 8-bit ASCII (the most significant bit being
zero) with one start, one stop and no parity.
In the run mode the new parameters will take effect at
the first angle after the press reaches the top of the
stroke after having received the DD command to
execute the new parameters. If the press is stopped or
is operating in the inch or micro inch mode then the DD
command to execute the new parameters is given, the
new parameters will take effect immediately. There are
no termination characters for the packets.
The press run data packet should contain the following
information, and in the order given:
1. ASCII characters AA.
2. Six independent angles and speeds defined in pairs.
The angles are in degrees and are defined in a
clockwise (CW) rotation with zero degrees at top
dead center. The speeds are in strokes per minute.
If it is desired to skip an angle, it may be
programmed to be 360.0 degrees and, since the
press will only accept angles from 0 to 359.9
degrees, it will skip the angle programmed for 360.0
degrees.
3. The seventh angle will be the angle that starts
slowing the press down to the creep speed after the
CES controller has received the stop-on-top contact
closure.
4. The eighth angle will be the angle to initiate the
contact that will allow the press control to set the
friction brake after the press has been at creep
speed and reaches this stop angle.
5. The angles will be four digits with an implied decimal
point, in tenths of a degree ranging from 0 to 359.9
degrees.
6. The speeds will be four digits, with an implied
decimal point, in hundredths of a stroke per minute.
7. The press run data should have the format indicated
in Table 2-5.
