6.2.7 Control Mode
1. Refer to section 7.2.7 for more details on how to use DMPID instruction.
2. When using PID parameters to set up control registers: PID control registers of AS04RTD-A are
retainable; however PID control registers of AS06RTD-A are not retainable.
6.2.8 Wiring
Precautions
To ensure the analog-to-digital module functions well and reliably, the external wiring must prevent noise.
Before you install the cables, follow the precautions below.
(1) To prevent a surge and induction, the AC cable and the input signal cables that are connected to the
ASRTD Series must be separate cables.
(2) Do not install the cable near a main circuit, a high-voltage cable, or a cable connected to a load
which is not a PLC. In addition, the cable must not be bound to a main circuit, a high-voltage cable,
or a cable connected to a load which is not a PLC.
(3) Ground shielded cables and hermetically sealed cables separately.
(4) Terminals with insulation sleeves cannot be arranged as a terminal block, so you should cover the
terminals with insulation tubes.
(5) Note: use cables with the same length (less than 200 m) and use wire resistance of less than 20
ohm.
