PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Modules with HART Communications 508 11.2.4.1 Channel Value Reference Data: ALG626 and ALG628 The module reports its input channel data in its configured Channel Value Reference input words, beginning at its assigned Channel Value Reference Address. Each channel value occupies 2 words, whether the channel is used or not: Channel Value Reference Address Contains this Input +0, 1 Channel 1 +2, 3 Channel 2 +4, 5 Channel 3 +6, 7 Channel 4 +8, 9 Channel 5 +10, 11 Channel 6 +12, 13 Channel 7 +14, 15 Channel 8 For Module IC695ALG626 Only: +16, 17 Channel 9 +18, 19 Channel 10 +20, 21 Channel 11 +22, 23 Channel 12 +24, 25 Channel 13 +26, 27 Channel 14 +28, 29 Channel 15 +30, 31 Channel 16 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. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Modules with HART Communications 509 11.2.4.1.1 Resolution and Range Type 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. Filter Frequency Range Type ±10 Vdc 0 to 10 Vdc, ±5Vdc, ±20 Vdc 0 to 5Vdc, 1Vdc 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 11.2.4.1.2 Channel Scanning These modules use 4 A/D converters to achieve the fastest possible channel scan times. The module has up to four acquisition cycles for each module scan. The acquisition cycles and For fastest scan times, always wire by acquisition cycle. For example, if only eight channels were used on the 16-channel module, IC695ALG626, channels 1, 2, 5, 6, 9, 10, 13, and 14 should be used for optimum performance. PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Modules with HART Communications 510 11.2.4.2 Input Channel Diagnostic Reference Data: ALG626 and ALG628 If the module is configured to use a Diagnostic Reference Address, it reports channel diagnostics status data to the CPU. The CPU stores this data at the Diagnostic Reference Address configured for this module. Use of this feature is optional. The diagnostics data for each channel occupies 2 words (whether the channel 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: PACSystems* RX3i System Manual Section 12 GFK-2314T Sept. 2019 Analog Modules with HART Communications 511 11.2.4.3 Module Status Reference Data: ALG626 and ALG628 The module can 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 Reference area configured for this module. 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. 11.2.4.3.1 Terminal Block Detection The module automatically checks for the presence of a Terminal Block. The TB LED indicates the state of the terminal block
