Abstract: A method includes receiving, at a first processing device of an input/output module (IOM), new firmware data for the IOM. The method also includes sending an output hold command from the first processing device to a second processing device of the IOM. The method further includes upgrading firmware of the IOM with the new firmware data using the first processing device and attempting a reboot of the first processing device. In addition, the method includes, in response to the output hold command and during the upgrading of the firmware and the rebooting of the first processing device, using the second processing device to cause a field circuit of the IOM to hold at least one previous output signal for one or more external devices.

Abstract: A system includes an input/output module (IOM) configured to interface with a field device. The IOM includes a terminal block including a plurality of inputs or outputs, each of the inputs or outputs configured to send and receive signals to and from the field device. The IOM also includes a plurality of temperature sensors, each of the plurality of temperature sensor configured to measure a temperature in a vicinity of the temperature sensor. The IOM also includes a connector configured to transmit the temperature of each of the plurality of temperature sensors to a processing device.
