Hey there Contractors and fellow Service Professionals!
Today we are covering the Allen Bradley 1747-L541 Series C PLC.
This is a SLC 500 SLC 5/04 CPU Processor. It has a user memory of 16K words total, which if we break it down is: 12K words for data or program and 4K words for data only.
The communication ports on this controller are DH+ & RS-232. The RS-232 port can also be configured for a DH-485 network.
A 1747-SN Remote I/O Scanner module can be used to configure I/O on a Universal Remote I/O link with this 1747-L541 processor. A 1747-SN Remote I/O Scanner module can also add a 1747-SDN DeviceNet Scanner module to configure I/O on a DeviceNet network.
You can use complementary I/O to configure 32 I/O chassis per Universal Remote I/O scanner. Otherwise, 16 I/O chassis per Universal Remote I/O scanner can be configured without complementary I/O. Lastly, a maximum of 63 DeviceNet devices can be addressed over the DeviceNet network with a DeviceNet scanner.
