The PC's ip address will need to be changed to 192.168.100.x where x is something other than 1:

If using 0 and 0 for the fixed ip address of 10.10.10.10 (per user manual), this will allow ping but not ACR-View to connect. This IP address is reserved for OS (firmware) downloads. With these settings, middle LED is green and bottom is flashing red is normal.
Is the PC connected direct to the IPA or through a switch or network? Try direct from the PC to the IPA to eliminate any networking issues. What version of Windows are you using? ACR-View6 works well with Windows7. Version 6.4.2 works with Windows10.
Blocked by firewall (can also block ping). Temporarily disable to the firewall on the PC or add both ACR-View6 (or PMM) and the comACRserver as exceptions to the firewall. Default locations are:

The bottom led will be OFF when not connected through ACR-View and ON (green) when connected.

When ACR-View is open, the comACR server opens in the task bar. When you close ACR-View, it should close.
Rarely, If it previously didn't close (such as Windows causing a crash and closing ACR-View abruptly), you can click there and Kill Server or do Ctrl+Alt+Delete and kill it in Windows task manager.
Then if you re-start ACR-View, it'll re-open a new instance of comACRserver.

Is this a new unit?
What is the serial number on the unit? If the unit is newer than January 26, 2017, it uses the new bootloader. The serial number is date coded YYMMDDxxxxxx. There was an issue with the previous bootloader. Cycling power would allow communications to run for some period of time before communications would stop. In the error log, this would be reported as a E51 hardware watchdog error.
Contact factory at emn.service@support.parker.comReset Utility:
There may be cases where a user program was created that is preventing communications. For example, a start-up program (PBOOT) includes the REBOOT command, which could cause the controller to repeatedly reset itself before communications can be established. The utility setting in the drive can be used to erase the programs and allow communications. With these settings, middle LED is green and bottom is flashing red is normal.
Set the rotary switches to 0 and 0 and cycle power. The IP address will actually be 192.168.100.1, but the controller will not fully load the operating system. Use a terminal application such as Hyperterminal or Putty and connect to to 192.168.100.1, port 5002. When connected the terminal will display the following:
