Note If DIP switch pin 1 is ON (up to 14 Sensors connected), the same internal pro-
cessing is performed as for an Analog Terminal. Therefore, calculate the I/O
response time as for the Analog Terminal. (Calculate the I/O response time as
a normal Terminal when pin 1 is OFF.)
When DIP switch pin 1 is ON and the following masters are connected, the
Sensor Communications Error Flag and Sensor Communications Flag are not
synchronized with the ON/OFF data for Units 1 to 8.
• C200HW-SRM21 (pre-version 1) and CQM1-SRM21 (pre-version 1) Mas-
ter Control Units.
• SRM1-C0 (pre-version 1) and SRM1-C0

• 3G8B3-SRM0
• C200PC-ISA
• SDD-CS1 Uniwire Send Unit (Manufactured by NKE Ltd.)
When a communications error occurs, for example, the data for Units 1 to 8
may be set to 0 before the Sensor Communications Error Flag has been
turned ON. If this is a problem, do not use the Unit with pin 1 set to ON (up to
14 Sensors connected).
