Analog electronics modules 4.3 Basics of analog value processing 4.3.3 Wiring unused channels of the analog input modules Rules Pay attention to the following instructions when wiring unused channels: • "Disable" unused input channels when setting parameters. • A disabled channel always returns the value 7FFFH. • The module cycle time is halved with the standard modules 2AI U, 2AI I 2WIRE, 2AI I 4WIRE, 2AI RTD Standard, 2AI RTD High Feature and 2AI TC Standard, 2AI TC High Feature. • The cycle time remains unchanged with the standard module 4AI I 2WIRE. • The cycle time remains unchanged at 1 ms with the HIGH SPEED modules 2AI U, 2AI I 2WIRE and 2AI I 4WIRE. • To maintain the allowable potential differences (UCM) bridges must be wired at the terminal module with the unused channels. This is required with the following modules: 2AI U Standard Analog Input Module 2AI RTD Standard, 2AI RTD High Feature, 2AI TC High Feature 2AI TC Standard 2AI U High Speed TM connection terminal Channel 0 Channel 1 1 2 3 4 5 6 7 8 ET 200S 4-24 Manual, 12/2005, A5E00514527-03
4.4 4.4 Analog electronics modules 4.4 Response of the analog modules during operation and if faults occur Response of the analog modules during operation and if faults occur 4.4.1 Influence of the power supply and the operating status on analog input and output values The input and output values of the analog modules are dependent on the power supply for electronics/sensors and on the operating state of the PLC (CPU of the DP master). The table below shows this dependency..
