9 FORM NO. L-21208-C-0908
70: Average Web Width Floating point number sent as integer * 10 in units of inches, read & write. Average Web
Width has a range of 1.0–400.0 inches.
Example 287.2 inches
Register 70: 11 (msb), 56 (lsb)
Average Web Width = ((11 * 256) + 56) / 10 = 287.2 inches
71: Maximum Roll Diameter Floating point number sent as integer * 10 in units of inches, read & write. Large Roll
Diameter has a range of 0.0–400.0 inches.
Example 40.5 inches
Register 71: 1 (msb), 149 (lsb)
Average Web Width = ((1 * 256) + 149) / 10 = 40.5 inches
72: Minimum Core Roll Diameter Floating point number sent as integer * 10 in units of inches, read & write. Core
Roll Diameter has a range of 0.0–50.0 inches.
Example 3.5 inches
Register 71: 0 (msb), 35 (lsb)
Average Web Width = ((0 * 256) + 35) / 10 = 3.5 inches

78: Display Units Sent as integer, read & write. Display Units has values of 0 for Imperial (English) and 1 for Metric.
Display Units has no effect on the RSTC as it only stores the value, and register values are communicated in Imperial
units only. Any Imperial to Metric or Metric to Imperial conversion is done in the HMI or PLC.
Example 1 – Metric
Register 77: 0 (msb), 1 (lsb)
79: Language Sent as integer, read & write. Language has values of 0 for English, 1 for Spanish, 2 for French, 3 for
German, and 4 for Italian. Language is used primarily to select the language in which the RSTC Operator Panel dis-
plays text and has no effect on the RSTC.
Example 0 – English
Register 78: 0 (msb), 0 (lsb)

ONTROL
80: Panel Write Enable Sent as integer, read & write. Panel Write Enable has values of 0 for disable and 1 for
enable. RSTC1000 sets this register to 0 whenever the RSTC Communications Software is connected to the
RSTC1000. An HMI can read this register and when equal to 0, any values sent by the HMI will be ignored by the
RSTC1000. After the RSTC Communications Software is disconnected, the RSTC1000 sets this register to 1 and
the HMI can again send values to the RSTC1000. This handshaking can be used to prevent two devices from sending
register value changes to the RSTC1000 at the same time.
Example 1 – Enable
Register 79: 0 (msb), 1 (lsb)
81: Manual/Automatic Mode Sent as integer, read & write. Manual/Automatic Mode has a value of 0 for Manual
and 1 for Automatic. When mode is set to Manual the RSTC1000 control output can be controlled using the Manual
Output Level register. When mode is set to Automatic the RSTC1000 control output is automatically controlled and
writing to Manual Output Level has no effect.
Example 1 – Automatic
Register 81: 0 (msb), 1 (lsb)
82: Manual Output Level % Sent as integer, read & write. Manual Output Level has a range of 0 to 100%. When
the RSTC1000 is in manual mode, writing to this register will immediately change the Control Output’s signal level.

67%
Register 82: 0 (msb), 67 (lsb)
