register:
A unit of memory for various types of data. A register is usually 16 bits wide.
ROM:
Read Only Memory. See EEPROM and EPROM.
route number:
Route numbers are used for expressing the position of standard and high-level link
units together. This numbering system is used to perform communication over layers,
such as when remote programming, etc. The route numberings are assigned starting
from the link unit at the slot nearest to the CPU as follows:
- FP3: “route 1”, “route 2”, “route 3”, “route 4”, “route 5” and “route 6”
including 3 standard link units and 3 high-level link units
- FP10S: “route1”, “route 2”, “route 3”, “route 4”, “route 5”, “route 6”,
“route 7” and “route 8” including 5 standard link units and 3
high-level link units.
Route 5 (ET - LAN unit)
Route 4 (ET - LAN unit)
Route 3 (MEWNET - W link unit)
Route 2 (MEWNET - P link unit)
Route 1 (C - NET link unit)
RS232C:
An EIA communication standard for data transmission media that is less than 15 m.
Most common serial communication standard.
RS422:
An EIA communication standard for data transmission media.
rung:
Term for a ladder program. A rung refers to the programmed instructions that drive
one output.
scan:
Time required to read all inputs, execute the program, and update local and remote
information.
self - diagnostic function:
