PLUS+1 CAN I/O Module Communications Protocol Technical Information Message Timing Information In the following section on message structures, the repetition time is specified. If the repetition time is set to zero, then the message is disabled and is not sent. If the repetition time is not zero, then the message is active and is transmitted periodically at the interval specified by the repetition time. (The following tables identify the repetition time as the Rate.) To change the repetition time, use the Configure Timing message (SUBCMD 12.) Some of the messages are referred to as optimized...

PLUS+1 CAN I/O Module Communications Protocol Technical Information Messages Based on the Sub-Identifier Supply (CMD 0) This frame is transmitted from the I/O device continuously with a default cycle time. CMD *Measured supply voltage in mV. †Measured sensor voltage in mV. ‡Measured shield voltage in mV. Dig_In (CMD 16) This frame is transmitted from the I/O device continuously with a default cycle time. This message has to be activated. By default, packed frames are used. CMD *Identifies the channel. †Actual pin status. Ana/Temp/Rheo (CMD 32) This frame is transmitted from the I/O device continuously...

PLUS+1 CAN I/O Module Communications Protocol Technical Information Messages Based on the Sub-Identifier Dig and Ana/Temp/Rheo Opt I (CMD 33) This frame is transmitted from the I/O device continuously with a default cycle time. This message is a packed frame and is activated by default if the device does have these inputs. Values not available on the I/O device are set to zero. CMD *Actual measured value of the first channel; mV in an analogue configuration; otherwise an Ω value. †Actual measured value of the second channel; mV in an analogue configuration; otherwise an Ω value. ‡ Bit pattern...

PLUS+1 CAN I/O Module Communications Protocol Technical Information Messages Based on the Sub-Identifier Dig/Ana Opt I (CMD 49) This frame is transmitted from the I/O device continuously with a default cycle time. This message is a packed frame and is activated by default if the device does have these inputs. Values not available on the I/O device will be set to zero. CMD *Actual measured value of the first channel in mV. †Actual measured value of the second channel in mV. ‡Actual measured value of the third channel in mV. §Bit pattern for the first 3 digital inputs; bit 0 is channel 0. Dig/Ana...
