SIOU Special Input /Output Unit.
Slave A device which receives data or instructions from a master device.
Slots Free areas within a rack to which units can be fixed.
Software switches Areas of memory employed by an SIO unit used to set operating parameters (similar in
manner to a hardware switch).
Space parity The parity bit is always set to 0.
Special Input /Output Unit A unit designed for a specific purpose.
SRM1 device type An OMRON PLC device supported by CX-Server.
Step Area An area of PLC memory containing a flag indicating the status of steps used within a
program.
Stop bits Bits indicating the end of transmission of each set of data bits; normally one or two bits,
they indicate the delay time between sending successive characters down the line.

Timer area An area of PLC memory containing program timers and their related completion flags.
Toolbus A network, either C-Toolbus or CV-Toolbus, allowing communications with a device
via the serial COM port of a personal computer (in a similar manner to SYSMAC
WAY). Data is transmitted along the network in binary format.
