Each channel occupies 2 words, whether or not the channel is used: Depending on its configured Channel Value Format, each enabled channel reports a 32-bit floating-point or 16-bit integer value to the CPU. In the 16-bit integer mode, the low word of the 32-bit channel data area contains the 16-bit integer channel value. The high word (upper 16-bits) of the 32-bit value is set with the sign extension of the 16-bit integer. This sign-extended upper word allows the 16-bit integer to be read as a 32-bit integer type in logic without PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 405 losing the sign of the integer. If the 16-bit integer result is negative, the upper word in the 32-bit channel data has the value 0xFFFF. If the 16-bit integer result is positive, the upper word is 0x0000. The 16-bit resolution module analog input data is stored in the CPU in 16-bit 2’s complement format as displayed in the following figure.

The CPU stores this data at the Diagnostic Reference Address configured for the module. Use of this feature is optional. The diagnostics data for each channel occupies two words (whether the channel is used or not): When a diagnostic bit equals 1, the alarm or fault condition is present on the channel. When a bit equals 0 the alarm or fault condition is either not present or detection is not enabled in the configuration for that channel. For each channel, the format of this data is: 9.9.6 Field Wiring: ALG233 Terminal Connection 1 User supplied 24V Input; provides loop power via 24VOUT terminal (pin 2) 2 +24V loop power tie point 3 Current Input, PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 409 9.10 Analog Input Module 8-/4-Channel Current/Voltage: IC695ALG608 Analog Input Module 16-/8-Channel Current/Voltage: IC695ALG616 IC695ALG616 I1 I2 I3 I4 I5 16 I7 18 19 I10 I11 I12 I13 I14 I15 I16 MODULE OK FIELD STATUS TB Figure 285: IC695ALG616 Non-Isolated Differential Analog Input Current/Voltage module IC695ALG608 provides eight single-ended or four differential input channels.
