RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 393 9.8.1.2 Module Status Data: ALG232 9.8.2 Channel Input Data: ALG232 The module reports its channel input data in its configured input words, beginning at its assigned Channel Value Reference Address. Each channel occupies 2 words (whether the channel is used or not): 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 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. MSB LSB 15 14 13 of this feature is optional. The diagnostics data for each channel occupies two words (whether the channel is used or not): PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 394 Ground Connections for 16-channel single-ended mode are displayed in Figure 278 and for 8-channel differential mode in Figure 279. Single-ended mode is the default operating mode for the module. Differential mode must be selected by configuration. 16 Single-ended Channels 8 Differential Channels Figure 278: Field Wiring Single-Ended ALG232 Figure 279: Field Wiring Differential ALG232 PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 396 9.9 Analog Input Module Advanced Diagnostics 16-Channel Current: IC694ALG233 MODULE 0K USER SUPPLY IC694ALG233 I1 I2 I3 I4 I5 16 I7 18 19 I10 I11 I12 I13 I14 I15 I16 Figure 280: IC694ALG233 The PACSystems RX3i 16-Channel Analog Current Input module, IC694ALG233, provides sixteen single-ended input channels. Each input can be configured using the configuration software for any of three input ranges: ▪ 4 to 20 mA ▪ 0 to 20 mA ▪ 4 to 20 mA Enhanced High and Low alarm limits are available on all ranges. In the 4 to 20 mA Enhanced range, a low alarm limit can be set up to detect input current from 4 mA to 0 mA, providing open-wire fault detection in 4 to 20 mA Enhanced applications. The module also reports module status and external power supply status to the CPU using its assigned program reference addresses. This module can be installed in any I/O slot that has a serial connector in an RX3i system. 9.9.1 Module Power This module consumes 120 mA from the 5Vdc bus on the RX3i backplane. It also requires 65 mA from a user-supplied +24Vdc supply, which must also supply current for each current loop employed. 9.9.2 Features ▪ Completely software-configurable, no module jumpers to set ▪ Open-circuit detection
