RS-232C Port Servicing Time

2. The startup mode will be PROGRAM mode or RUN mode, depending on
the Connecting Cable being used.
Connecting Cable
CS1W-CN114 + CQM1-CIF01/02
CS1W-CN118 + XW2Z-200/500S(-V)
CS1W-CN226/626
CS1W-CN118 + XW2Z-200/500S-CV
Make the settings shown below to determine whether, when the power supply
is turned ON, the Forced Status Hold Bit (SR 25211) and/or I/O Hold Bit
(SR 25212) will retain the status that was in effect when the power was last
turned OFF, or whether the previous status will be cleared.
SR 25211 setting
0: Clear status
1: Retain status
SR 25212 setting
0: Clear status
1: Retain status
Default: Clear both.
The Forced Status Hold Bit (SR 25211) determines whether or not the forced
set/reset status is retained when changing from PROGRAM mode to MONI-
TOR mode.
The I/O Hold Bit (SR 25212) determines whether or not the status of IR bits
and LR bits is retained when PC operation is started and stopped.
The following settings are used to determine the percentage of the cycle time
devoted to servicing the RS-232C port.
Servicing time setting enable
00: Disabled (5% of the cycle time)
01: Enabled (setting in bits 00 to 07 used)
Servicing time (%, valid when bits 08 to 15 are set to 01)
00 to 99 (BCD, two digits)
Default: 5% of cycle time
Example: If DM 6616 is set to 0110, the RS-232C port will be serviced for
10% of the cycle time.
The minimum servicing time is 0.256 ms.
The entire servicing time will not be used unless processing requests exist.
