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. PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 421 9.11.2.1 Resolution and Range Types: ALG608 & ALG616 The actual resolution for each input depends on the Range Type and A/D Filter Frequency configured for that channel. At higher Filter Frequencies, input resolution decreases. The approximate resolution in bits for each Filter Frequency and Range Type are displayed in the following table. Resolution (in bits) Filter Frequency Range Type ±10 Vdc 0 to 10 Vdc, ±5Vdc, ±20 Vdc 0 to 5Vdc, 1 to 5Vdc, 0 to 20mA, 4 to 20mA 8 Hz 18 17 16 12 Hz 17 16 15 16 Hz 17 16 15 40 Hz 16 15 14 200 Hz 15 14 13 500 Hz 14 13 12 9.11.2.2 Channel Scanning: ALG608 & ALG616 These modules use 4 A/D converters to achieve the fastest possible channel scan times. The module has up to four acquisition cycles Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 422 9.11.2.3 Channel Diagnostic Data: ALG608 and ALG616 In addition to the input data from field devices, the module can be configured to report channel diagnostics status data to the CPU. 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 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: PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 423 PACSystems* RX3i System Manual Section 10 GFK-2314T Sept. 2019 Analog Input Modules 424 9.11.2.4 Module Status Data: ALG608 & ALG616 The module can also optionally be configured to return two bits of module status data to the CPU. The CPU stores this data in the 32-bit Module Status Data reference area configured for the module. 9.11.2.4.1 Terminal Block Detection The module automatically checks for the presence of a Terminal Block. The TB LED indicates the state of the terminal block of the module. It is green when the Terminal Block is present or red if it is not. Faults are automatically logged in the CPU I/O Fault table when the terminal block is inserted or removed from a configured module in the system. The fault type is Field Fault and the fault description indicates whether the fault is a "Loss of terminal block" or an "Addition of terminal block". If a Terminal Block is not present while a configuration is being stored, a "Loss of terminal block" fault is logged. Bit 1 of the Module Status Reference indicates the status of the terminal block. To enable Module Status reporting, the Module Status Reference must be configured. During operation, the PLC must be in an I/O Enabled mode for the current Module Status to be scanned and updated in reference memory. 9.11.3 Field Wiring: ALG608 & ALG616, Single-Ended Mode The following table lists wiring connections for Non-Isolated Analog Input Modules in Single-ended mode. Single-ended mode is the configured default operating mode. Terminal IC695ALG608
