6.2 Using Programs in Normal System Configuration
This section describes program examples based on the following system configuratiion
and conditions.
(1) System configuration
Figure 6.2 Example of system configuration
(2) Setting conditions for the intelligent function module switch setting
(3) Programming conditions
(a) Use the following temperature conversion system for each channel.
• CH1: Sampling processing
• CH2: Count average (5 times)
• CH3: Primary delay filter (Time constant 960ms)
(b) Use the following function at each channel.
• CH2: Warning output function
• CH3: Warning output function
(c) Use the following setting for the Conversion setting for disconnection detection of
CH1 to CH3.
• CH1 to CH3: Down scale (-352.0 ) [Default setting]
(d) When a write error occurs, the corresponding error code is output to an output
module in BCD value.
