Firmware used in production

The actual COSinus FW is available from the COSinus firmware page.

Good to know

  • PCD2.M4x60 with hardware version A and B dosen't support the use of analog/ISDN or GSM modems.To use modems on a PCD2.M4x60 it's necessary that the PCD2.M4x60 have a least a hardware version C and the FW 1.26.15, see FAQ 101986
  • To support the PCD7.W600 it's also necessary to use the hardware C or newer of the PCD2.M4x60.



PCD2 / M4x60

  • On a PCD2.M4560 or PCD3.W5560, why the measured PT100 temperature values are not correct if the PT100 sensors are connected to PCD2.W220Z18 or PCD3.W220Z18 modules? (FAQ #102052)
  • Why on a PCD3.M5/6xxx or a PCD2.M45xx the battery LED is switched on and the battery error message is activated in the application program after a new battery was inserted? (FAQ #102039)
  • What are the differences between the COSinus firmwares FW 1.28.11 and FW 1.28.37? (FAQ #102010)
  • It’s possible to use the ‘old’ PCD7.F1xx module (not the PCD7.F1xxS) on PCD1.M2 and PCD2.M4x60 CPU’s? (FAQ #102005)
  • It’s possible to use the PCD7.W600 analogue input module on a PCD2.M4x60? (FAQ #101993)
  • Why the PCD7.W600 analogue input module doesn’t work on a PCD2.M4x60? (FAQ #101992)
  • What are the differences between the COSinus firmwares FW 1.24.67 and FW 1.26.31? (FAQ #101987)
  • Why it’s not possible to communicate with a modem which is connected to a PCD2.M4x60? (FAQ #101986)
